Intel DQ35JO latest BIOS update breaks Linux

Category: Technology / Tags: no tag / Add Comment

Recently I tried to upgrade the BIOS of my Intel DQ35JO motherbord, with which I’ve been pretty happy. After the upgrade to the most recent BIOS (11.22) my Linux kernel (2.6.28-16-generic/amd64) failed to boot, producing the following error message:

PANIC: early exception 0e rip 10:ffffffff8041f9b4 error 2 cr2 ffff87ffffffffff

Downgrading the BIOS to a somewhat older version (but newer than what a started with) solved the issue again. So I set out to finding out in what BIOS revision the regression snuk in:

  • 09.42 works
  • 09.91 works
  • 10.16 works
  • 10.56 fails
  • 11.22 fails

So when upgrading your Intel DQ35JO motherboard, I recommend you stick with BIOS version 10.16 for the time being. I reported this issue to Intel, and I was told the issue would be passed along to the engineering department (with little guarantee this would be fixed). But Intel being Intel I have good hopes this will get resolved with some patience…
