    How to install Prereleases and Report Bugs

    in Prereleases

    Posted

    So I'm loving unRAID so far now that I've "gotten my feet wet".  One issue I keep running into with each new RC, if I attempt to apply the update within the OS itself, it never fully reboots... and then when I finally hard shut it down and power it back on, the system just stays at a black screen.  However if I shut it down, take the USB and backup the config folder, then use the USB Creator tool and install the same RC that I'm attempting to upgrade to, and then copy the config directory back over to the drive, then boot things up, it has no problems.  Any thoughts?

    Upgrade completed, upon next boot went to a black screen.  During my rc2 install I chose to allow UEFI boot.

    I ended up yanking my USB, manually copying out the config folder, running the updated USB Creator over it making sure to re-use existing name and setting it to use UEFI boot, then copied back over the config directory, then it booted.

     

    Since RC3 is just using kernel 15.15,  I'm not even going to bother with trying to use iGPU passthrough to Plex or Handbrake.  Once it goes to 15.16.x then I'll give it a shot - unless someone can confirm that RC3 iGPU passthrough to Plex/Handbrake actually works and does hardware transcoding/QSV.

    I ran a quick test tonight after upgrading to 6.10.0-rc3 and I was able to lock up the server on 3 separate occasions when transcoding via plex. Now I was actually able to see something on my syslog this time around (see below) unlike previously, I am assuming this is the same issue unless I have something else going on that is causing this? I am running a 12600k.

     

     

    It should be noted that the release notes about the kernel are:

    Linux Kernel

    Upgrade to [rc3] Linux 5.15.27 kernel which includes so-called Sequoia and Dirty Pipe vulnerability mitigations.

    …. So it’s not yet on. 15.16,x - which I believe is what contains the supported iGPU drivers for 12th gen.  Let’s not get our hopes up yet if that’s the case.

    Intel GPU Top Plugin installed, no other modifications performed

    Plex using software transcoding, not passing /dev/dri device through

     

    Every morning at 2am I get 2 segfaults from Plex Media Scanner.  I've posted in Plex's forum, but no response yet.

     

    No crashes in 18 days, running rock stable.  I did reboot when installing the new BIOS, so my current uptime is 9 days at the moment... At 10 days that will be the longest I've had the computer booted without a lockup.

    No, I am at 50+ days of uptime since removing the Intel-GPU-top and GPU Statistics plugins. 

     

    I also recently removed the CoreFreq plugin as there have been several reports of it locking up servers.  This was not in response to a crash, just an extra precaution.

    What CPU are you running?  Are you using iGPU passthrough to Plex for transcoding?

    Can someone please simplify what needs to be done? Im running a 12600K with Z690 and get system hangs every couple of hours.

    I made an empty /boot/config/modprobe.d/i915.conf file, anything else that needs to be done? Still getting seemingly random system hangs.

     

    Im not sure i understand. How do i do this?

    “blacklist i915” should be the content of that file I believe.  After 9 days and hours worth of Plex usage, mine finally locked up.  I’m taking /dev/dri out of the container and seeing if that smoothes things out.  Hopefully this is resolved when better driver support comes out.  Also, QSV for the 12600k seems to be non-existent at this point or at least craps out when encoding using Handbrake in unRAID…

    No, it was just the solution to remove the file from modprobe.d when RC3 arrives would stop iGPU working for Alderlake as Unraid will load the driver without the force probe. Likely to be when Kernal 5.16 is added to unraid that the native support will be in the i915 driver without the force probe then this work around can be removed. Force Probes is enabling support for a device, but it is not full release code, more than beta but maybe not 100% stable or needs further tweeks for new architecture. 

    Gotcha, thanks!  So for rc2 we need to leave it in for things to work - but they may still encounter hangups periodically *possibly* until kernel 5.16 finds its way into unRAID.  At that time we will most likely be safe to drop blacklisting the i915 driver...correct?

    For Alder Lake you need the following option, this was the case for Rocket Lake but options values are different.

     

    i915.force_probe=4680 

     

    So one of the following needs to be done for the iGPU.

     

    1. you can add to Syslinx i.e. append initrd=/bzroot,/bzroot-gui isolcpus=2-11 acpi_enforce_resources=lax i915.force_probe=4680 and Unraid will load driver correctly.

    2. From RC2 onwards, Blacklist the driver in modprobe.d and install Intel gpu top to load driver with correct probe.

    3. Add options to modprobe file. options i915 force_probe=4680 

     

    Otherwise the driver will not load for UHD770 iGPU.

    I'm probably misunderstanding something... I'm running an i5-12600k with unRAID 6.10.0 rc2.  In my /etc/modprobe.d/i915.conf file I have "blacklist i915", and I have the intel gpu top installed.  If I'm understanding what you're saying, this should resolve hangups...correct?

    Ye ifgure out it was a microcode bug but kidna scary sometime the VM and the server does crash rarely i fear it might be related to the very bad gigabyte z690 bios and those problem

    Running into the same message in my logs while booting.  I have some significant instability, but it is possibly appearing to be RAM/motherboard related (either incompatibility or memory error... but MemTest can't seem to find anything with 8 passes...).  UnRaid 6.10-rc2, Asus Prime Z690-P D4, i5-12600k, 2 kits of 2x16GB G.Skill F4-3200C16D-32GTZR, latest BIOS (0605).  Ever have any luck figuring it out?
