[LU-2500] replay-single test 48 lockup

Sat, 22 Dec 2012 00:42:15 +0000

I am having replaye-single test 48 consistently hanging.
There's a stack-trace for a hung task in the log and that task never finishes it looks like:

[246707.608040] LNet: Service thread pid 16278 was inactive for 40.00s. The thread might be hung, or it might only be slow and will resume later. Dumping the stack trace for debugging purposes:

I have a crash dump for such occurence as well
This dump is with patch from lu2285 applied, but also happens without lu2285 patch in.
