Subject: AIO/DIO lockup/crash

Hi guys,

I'm getting this (and various variations thereof - like crashing in the
PI chain code on -rt) when running aio-dio-invalidate-failure for a few
hours.

(dual core opteron - single spindle - ext3)

Is this a known issue?

I'll run the same on current -git overnight to see if it went away :-)
