Hi all,
lately starting from kernel 2.6.28-rc6-00142-g9bd062d I'm getting this traces:

"irqpoll" option)

Actually now that i notice all the log seems the same except the
kernel version that's from git. After this traces interrupt 16 is not
incrteasing in /proc/interrupts anymore (as suggested by the last log
line) and Xorg is all slugish, barely usable. Noticing that there were
modifications on the i915 driver i waited till now to report this but
none of the last patches got rid of this issue so here is the log.
Right now i booted adding irqpoll on the command line and i see in
dmesg this one:
Kernel command line: root=/dev/sda2 rootflags=data=writeback irqpoll
Misrouted IRQ fixup and polling support enabled
This may significantly impact system performance
Though everything seems normal for now. The trace happens usually when
the system is under load but it's not that predictable so for now i
cant tell if using irqpoll is avoiding hitting this issue. I'll let
you know if it happens again.
Just ask for info or whatever patches to test ecc. is needed, i'll be
glad to help.
And of course thank you guys for your work.
Frederik
This bug was first reported a few weeks ago and it seems still hasn't
been resolved for some. The bug report can be found here,
