  1. No, I did not. At this point I don't have it in me to deal with more cmos resets. I've also been dealing with another issue that affects this board on unraid (kernel panics and lock ups every 12 hours or so). This board and unraid have been a bad combo so far.
  2. Same. I'm assuming you have unraid load igpu drivers for hw transcode? Once those drivers are loaded, the motherboard disables vga, which is connected to the IPMI for ikvm. See here for a broader discussion on that:
  3. Here we go again. Before I could get to my server, it's locked up again. Barely lasted 12 hours. No br0 static IP containers. I have a couple on br0.10 vlan. "host access to custom networks" was enabled iirc. Here's the last of the log sent to remote syslog before the crash: May 1 13:35:22 Tower kernel: BUG: unable to handle page fault for address: 00000000ffffffae May 1 13:35:22 Tower kernel: #PF: supervisor read access in kernel mode May 1 13:35:22 Tower kernel: #PF: error_code(0x0000) - not-present page May 1 13:35:22 Tower kernel: PGD 800000061069f067 P4D 800000061069f067 PUD 0 May 1 13:35:22 Tower kernel: Oops: 0000 [#1] SMP PTI May 1 13:35:22 Tower kernel: CPU: 6 PID: 20760 Comm: node Tainted: G W 5.10.28-Unraid #1 May 1 13:35:22 Tower kernel: Hardware name: Supermicro Super Server/X11SCA-F, BIOS 1.4 09/03/2020 May 1 13:35:22 Tower kernel: RIP: 0010:nf_nat_setup_info+0x129/0x6aa [nf_nat] May 1 13:35:22 Tower kernel: Code: ff 48 8b 15 ef 6a 00 00 89 c0 48 8d 04 c2 48 8b 10 48 85 d2 74 80 48 81 ea 98 00 00 00 48 85 d2 0f 84 70 ff ff ff 8a 44 24 46 <38> 42 46 74 09 48 8b 92 98 00 00 00 eb d9 48 8b 4a 20 48 8b 42 28 May 1 13:35:22 Tower kernel: RSP: 0018:ffffc9000023c700 EFLAGS: 00010202 May 1 13:35:22 Tower kernel: RAX: ffff88815d423e06 RBX: ffff8881147c57c0 RCX: 0000000000000000 May 1 13:35:22 Tower kernel: RDX: 00000000ffffff68 RSI: 00000000c2955a34 RDI: ffffc9000023c720 May 1 13:35:22 Tower kernel: RBP: ffffc9000023c7c8 R08: 00000000f7570d7c R09: ffff8881010870a0 May 1 13:35:22 Tower kernel: R10: ffff8886a70e0388 R11: ffffffff815cbe4b R12: 0000000000000000 May 1 13:35:22 Tower kernel: R13: ffffc9000023c720 R14: ffffc9000023c7dc R15: ffffffff8210b440 May 1 13:35:22 Tower kernel: FS: 000015372ba5eb48(0000) GS:ffff88902c380000(0000) knlGS:0000000000000000 May 1 13:35:22 Tower kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 May 1 13:35:22 Tower kernel: CR2: 00000000ffffffae CR3: 00000001fee5c001 CR4: 00000000003726e0 May 1 13:35:22 Tower kernel: DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 May 1 13:35:22 Tower kernel: DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 May 1 13:35:22 Tower kernel: Call Trace: May 1 13:35:22 Tower kernel: <IRQ> May 1 13:35:22 Tower kernel: ?

  4. Thanks, that's what I was going to try next. Btw do you know which nic is the one shared with ipmi? Is it the igb one or the e1000e one as shown in unraid gui?
  5. I was on a Supermicro X9SRL-F board with an old Xeon E5 and no issues on 6.9.2. I just swapped the mobo with a Supermicro X11SCA-F and every few hours I get a kernel panic and the nf_conntrack message. It locked up once yesterday (no console, no ssh access, etc.) and required a hard reset and parity check. Today I moved the 2 containers off of br0 into br0.10 (vlan) and 2 hours later I got the kernel panic again (no lock up, though). I have 2 network interfaces bonded in this case.

  6. Yeah, I spent way too much time on way too many cmos resets. I finally got it to a state where it seems to be stable (after several power cycles). At least now I have ikvm access to bios and can see most of the unraid boot process; and hw transcode works. I guess I can live without console access over ikvm.
  7. As a last ditch effort, I tried to bump the memory limits under graphics settings to see if it would fix the black screen issue with onboard oprom set to efi, but now it is getting stuck on PCI enumeration before you can get into bios. I officially give up. Going back to legacy boot with everything else legacy and pci primary set to onboard. At least I'll have bios access and most of the boot process on ikvm (modprobe is the last line in the go file). I don't have it in me to clear cmos and start over one more time.
  8. Hey guys, I just got the X11SCA-F and put in an E-2146G. It came with bios version 1.4. I followed all the advice and directions in this thread and nothing seems to let me have ikvm and /dev/dri at the same time. And there is one specific change that locks me out of all video output (even bios) and forces me to clear cmos and start over. Perhaps this bios version is really buggy. Here are my general observations: By default, boot is set to "dual", which should allow both legacy and uefi. When boot is set to "dual" or "legacy", most everything else is also automatically set to legacy (including the onboard video oprom option mentioned in this thread). When boot is set to "uefi", most other options also switch to uefi automatically (including onboard video oprom) Here is a list of what happens with different settings: Boot set to "dual", trying to load unraid with legacy, it gets into a boot loop where it goes through all the steps of the boot process and when it's time to boot into unraid, it resets. When I tried to boot unraid in uefi with that, same thing happened unless I selected the boot option manually, in which case it booted fine. Something about the "dual" boot setting just doesn't seem to work. Boot set to "legacy", primary display in bios set to pci, primary pci set to onboard and internal graphics set to enable, unraid boots via legacy just fine. ikvm works right up until modprobe and then it drops (tried with and without monitor attached) Boot set to "uefi", primary display in bios set to pci and internal graphics set to enable, unraid boots via uefi just fine. ikvm works right up until modprobe and then it drops (tried with and without monitor attached). One interesting thing is that when boot is set to uefi, the options "primary pci" and "primary peg" disappear from graphics settings, very strange. Now if boot is set to legacy, and I follow this thread's advice and set onboard video oprom to uefi, I can see the boot process with the Supermicro background, but it goes to a black screen (sometimes green and sometimes red) when it tries to boot into unraid or bios. This I tried with and without a monitor attached, and the same thing happens. I can no longer go into the bios because hitting "Del" results in the same black screen. The process goes on in the background (because unraid web gui does come up if I wait long enough). But I have no display. I tried hdmi as well, which displays nothing. And vga displays a faulty signal (according to a monitor). The only solution to this is to clear cmos and start over. I eveb tried this without ever plugging a monitor in at all after resetting cmos, so that's not it. So in a nutshell, legacy booting with onboard video oprom set to uefi completely breaks vga display, requiring a cmos clear. Legacy booting with bios set to pci and, pci default set to onboard and onboard video enabled, ikvm works up until modprobe. Uefi booting with bios set to pci and onboard video enabled (no option for default pci), ikvm works right up until modprobe. So I'm going with the final option for now, at least I can see to boot process and get into bios, and utilize hw transcode. But, it irks me that with uefi boot, the option for default pci is not there. I'm not sure what will happen when I plug in another gpu for passthrough. It will perhaps switch to that for output and make me lose ikvm for boot process? Who knows. In any case, this board looks awesome on paper, but the bios and the settings (and the bugs) are incredibly annoying and time consuming to try and figure out. I wish there were more options for affordable server boards with ipmi/ikvm.
