Hello Pedram,
Bugzilla seems to be AWOL today so lets continue the discussion by email.
I noticed this issue is still pending. It is weird that the problem
persists between cold reboots (which points to a hardware error) but is
also dependent on the kernel version in use (which points to a software
error).
Would you happen to have additional cards to try ?
Can you email a log file containing the 'fifo 0: descriptor error' bug ?
Do you think that temperature has an effect on the bug occurring, does
it make a difference if you let your machine cool down between reboots ?
I identified an issue today that gives the same error message, but that
issue only occurs on 64 bit platforms, and you report that you also see
it on 32 bit platforms.
Can you run a memory test on your system, e.g. one that tests the memory
during an overnight test ? Reason is that the error message occurs
because the DMA engine read invalid data from memory.
Thanks, Roland.

Hi Henry,
I have filed this as bug 40972 along with the answers to your
questions: https://bugzilla.kernel.org/show_bug.cgi?id=40972
In short, yes, the error does appear immediately after a full
power-off shutdown as soon as I bring the interface up after loading
the module. Not always, but more often than not.
I am running 32-bit but have used 64bit prior. I reinstalled my system
thinking that it was a problem with 64-bit libraries. The full lsmod
is on the bug report.
I am currently running fine again. I will keep my laptop on throughout
the day in the hopes that it goes down. Let me know if you need
anything else.
Thanks so much
Pedram
