Hi,
As with -rt3, I was able to capture one more crash trace, via serial
console, with nmi_watchdog=1.
Yes, current 2.6.22.1-rt4 is still locking-up on my ix86 SMT/SMP boxes.
I'll have to wait for some hours of uptime and normal desktop use and
then it just locks-up without warning.
Last couple of occurrences were all while browsing with firefox
(2.0.0.5) or using openoffice.org (2.0.4) but in rare and
non-deterministic fashion I must say.
It looks very similar to the previous ones I've reported before for
-rt3, but I am no expert in these things.
