Hi,

 

I am facing random issues with drives not being recognized and in the logs I see errors like BFMS emhttpd: device /dev/sdi problem getting id. The drives are connected to an LSI SAS3 Controller and an Expander.

 

On Unraid 6.12.13 all drives function flawless without any issues and are recognized on every restart.

 

I tried enabling/disabling SV-IO and adding pci-realloc=off to the syslinux.cfg but the situation does not change.

 

I am hoping that someone might have an idea what is going on. The Diagnostic files can be found attached.

 

Also the reboot does not work properly. The reboot hangs everytime at rc.6 Rebooting.

IIRC there was another user with the same issue, and for him, it was caused by the iGPU driver, I and see a call trace related to it in your diags, try blacklisting the driver to see if the disks come up, but obviously if the iGPU is used for something other than monitor output it won't be available:

 

echo "blacklist i915" > /boot/config/modprobe.d/i915.conf

 

Then reboot.

 

 

 

 

Thanks - the iGPU is essential for my setup since I use it for transcoding in Plex and Emby. The other card (RTX A4000) is solely used for AI purposes.

 

Are there any custom/updated drivers available or is there a fix in a later version? I will give the blacklisting a try to see if that is indeed the root cause.

If that the issue, and I believe it is, a newer kernel with a new driver may help, like with Unraid 7.1, which should be available soon.
