Dear all,
What is the status with respect to this problem? I see that in the
current -rt patch the problematic code piece is different. I
personally haven't tried to reproduce this myself on a more recent
kernel, but I just got a report from one of our users who experienced
the same problem with 2.6.19-rt15 and RT preemption (desktop
preemption works fine).
Should the latest -rt patches be fixed with respect to this issue? If
so I'll try and test them, otherwise I omit the effort.
it's not fixed yet. Could you try the patch below?
I just compiled & installed 2.6.20-rc6-rt2, and I saw that this patch
was in the -rt2 patch, so I gave real-time preemption a shot. It seems
to work, I don't experience lockups anymore.
Thanks for the fix,
Pieter
