Description Bryan O'Sullivan 2006-11-03 08:51:04 UTC

Most recent kernel where this bug did not occur: 2.6.18
Hardware Environment: x86_64, QLogic IBA6110 chips
Problem Description:

The ipath driver causes an MCE after Eric's genirq and HT irq changes in early
October.  I'm filing this bug to track the issue.  We don't seem to have an
Infiniband category, so this will have to do.

Yep.  The problem was that the driver never properly handled interrupts and I
broke the hack it was using.  Hopefully we can find a way to handle this
properly soon.

Fixed in git.
