We are pleased to announce the next update to our new preempt-rt
series.
- Forward to 2.6.31.4
- Handle futex spurious wakeups
- slab fixes for NUMA (peterz)
The slab problem is still not completely resolved. It's hard to
reproduce and was only seen on Nehalem dual socket systems so far. If
you have such a machine you might help providing a back trace, just run
while true; do hackbench N; done
until it explodes. Adjust N to your system, the larger the
better. Make sure you have a serial console to capture the oops.
