msobon Posted March 5, 2012 Share Posted March 5, 2012 Hi Folks, ***Update** A solution/workaround found see below, this applies to latest Unraid 6 as well, THE Disabling IRQ issue affects my system where it comes down to a snails pace once "Disabling IRQ # occurs As mentioned in the subject I'm experiencing issues with virtualized unraid and IRQ #18 message which brings everything to a screeching halt of snails pace. The build is very similar to JohnM's Atlas build: http://lime-technology.com/forum/index.php?topic=14695.0 My Build: Intel Xeon E3-1230 SUPERMICRO MBD-X9SCM-F-O LGA 1155 Intel C204 Kingston 16GB 2x (2 x 4GB) 240-Pin DDR3 SDRAM ECC Unbuffered 3 X SUPERMICRO AOC-SASLP-MV8 In terms of the confirguration I followed Johnm's guide to the T and everything seems to work fine but however I get Disabling IRQ error, it appears random does not seem to be related to running 3x SUPERMICRO AOC-SASLP-MV8, I Ran 2 and had experienced the same issue. Below is extract from syslog.txt: Mar 4 15:38:53 MediaTower kernel: irq 18: nobody cared (try booting with the "irqpoll" option) Mar 4 15:38:53 MediaTower kernel: Pid: 0, comm: swapper Tainted: G W 2.6.32.9-unRAID #8 Mar 4 15:38:53 MediaTower kernel: Call Trace: Mar 4 15:38:53 MediaTower kernel: [<c10451cf>] __report_bad_irq+0x2e/0x6f Mar 4 15:38:53 MediaTower kernel: [<c1045305>] note_interrupt+0xf5/0x13c Mar 4 15:38:53 MediaTower kernel: [<c1045a14>] handle_fasteoi_irq+0x5f/0x9d Mar 4 15:38:53 MediaTower kernel: [<c1004a82>] handle_irq+0x1a/0x24 Mar 4 15:38:53 MediaTower kernel: [<c1004285>] do_IRQ+0x40/0x96 Mar 4 15:38:53 MediaTower kernel: [<c1002f29>] common_interrupt+0x29/0x30 Mar 4 15:38:53 MediaTower kernel: [<c1008160>] ? default_idle+0x2d/0x42 Mar 4 15:38:53 MediaTower kernel: [<c1001a14>] cpu_idle+0x3a/0x4e Mar 4 15:38:53 MediaTower kernel: [<c128a8bf>] rest_init+0x53/0x55 Mar 4 15:38:53 MediaTower kernel: [<c13f580c>] start_kernel+0x27b/0x280 Mar 4 15:38:53 MediaTower kernel: [<c13f5091>] i386_start_kernel+0x91/0x96 Mar 4 15:38:53 MediaTower kernel: handlers: Mar 4 15:38:53 MediaTower kernel: [<c11ead61>] (usb_hcd_irq+0x0/0x5b) Mar 4 15:38:53 MediaTower kernel: [<f84bf24e>] (mvs_interrupt+0x0/0x66 [mvsas]) Mar 4 15:38:53 MediaTower kernel: Disabling IRQ #18 Full Syslog: http://www.sobon.ca/Unraid/syslog.txt My cat /proc/interrupts: My Syslinux.cfg with irqfixup and irqpoll added in attempt to remedy the issue with no luck: default menu.c32 menu title Lime Technology LLC prompt 0 timeout 50 label unRAID OS menu default kernel bzimage append initrd=bzroot irqfixup rootdelay=10 irqpoll label Memtest86+ kernel memtest Any help would be appreciated, keep in mind this is a virtualized unraid not sure what bios changes are possible. I managed to find a workaround/Solution, keep in mind this is not a root cause fix, but a better known fix aside from rebooting the box: Adding "noirqdebug" into the syslinux.cfg file: default /syslinux/menu.c32 menu title Lime Technology prompt 0 timeout 50 noirqdebug label unRAID OS menu default kernel /bzimage append initrd=/bzroot label unRAID OS Safe Mode (no plugins) kernel /bzimage append initrd=/bzroot unraidsafemode label Memtest86+ kernel /memtest Quote Link to comment
prostuff1 Posted March 5, 2012 Share Posted March 5, 2012 Try with either irqfixup OR irqpoll but not both at the same time. You can see if there is a BIOS update available also. Disable anything not used. I had a similar issue on my ESXi build but irqpoll seems to have fixed mine. You can try running a beta version instead of 4.7 and that might help/fix the issue. I am running 5.0b6a (soon will be upgraded most likely) and irqpoll works. Quote Link to comment

msobon Posted March 7, 2012 Author Share Posted March 7, 2012 Update, Irqpoll did not fix the issue sil getting disabling IRQ #. Any suggestions? Quote Link to comment
StevenD Posted March 7, 2012 Share Posted March 7, 2012 Im having a similar problem on my new openfiler box. its killing my fiber card. Quote Link to comment
BobPhoenix Posted March 8, 2012 Share Posted March 8, 2012 I have your exact setup minus one MV8. I will check tonight and see if I see the same error but I do not believe it is happening. It certainly isn't affecting speeds any if I do have the same errors in my log. 15 2TB drives currently. Quote Link to comment
msobon Posted March 8, 2012 Author Share Posted March 8, 2012 It almost looks like a glitch or bug on syslinux, I was able to find this issue outside of the unraid forums as well. Does anyone know what exacly triggers this? I can't seem to pinpoint it and it's getting annoying to reboot on a daily basis to use. Quote Link to comment
msobon Posted March 10, 2012 Author Share Posted March 10, 2012 I upgraded to the latest beta hoping that would fix the issue however it has not, unraid worked fine for about 30 hours and then I got his with Disabling IRQ# again. My patience is running out, there has to be a solution for this. Quote Link to comment
Johnm Posted March 10, 2012 Share Posted March 10, 2012 I'll look in my past logs. as far as i know I have not seen these. Quote Link to comment
msobon Posted March 21, 2012 Author Share Posted March 21, 2012 It looks like I was able to partially solved the IRQ issue, I used the "noirqdebug" option which doesn't let the debug disable IRQ's however this does not really point to why it's happening if anyone has any other ideas let me know.

BobPhoenix Posted March 22, 2012 Share Posted March 22, 2012 I actually got the errors you described in OP. For me I just restarted the VM and the really slow access went away and I didn't have any of the IRQ#18 errors in the new log. Hoping it will always be that easy to clear. Quote Link to comment
joelones Posted November 8, 2012 Share Posted November 8, 2012 I seem to be getting a similar error, documented here: http://lime-technology.com/forum/index.php?topic=23417.msg206539#msg206539 Using a SASLP-MV8 and I only noticed this sporadically on shutdowns. When I do see "Disabling IRQ #16" message, the subsequent reboot I always lose the same disk on the MV8. Extremely weird. X8SIL-F, X3430 M1015 on pci-e slot #2 MV8 on pci-e slot #3 Quote Link to comment
msobon Posted January 29, 2016 Author Share Posted January 29, 2016 Also work on Unraid 6.x, note some updates overwrite the syslinux.cfg file which will need to be reapplied. Quote Link to comment
