Created attachment 517292 [details] Kernel panic screenshot +++ This bug was initially created as a clone of Bug #172907 +++ Description of problem: When calling the function clock_gettime() with parameter CLOCK_MONOTONIC, the kernel sometimes crashes, producing the following error
Problem appears to have been reported against upstream around 2.6.21: https://lkml.org/lkml/2007/3/2/20 with a simple patch fixed and committed: http://marc.info/?l=linux-kernel&m=117210430112543&w=2 Was previsouly reported against Fedora 4 (2.6.14-1.1637_FC4), but was assumed to have been fixed (apparently it just became harder to reproduce): https://bugzilla.redhat.com/show_bug.cgi?id=172907
Charlie, How reproducible this problem is for you? How do I reproduce it?
(In reply to comment #2) > Charlie, How reproducible this problem is for you? How do I reproduce it? From our application engineer: [our program] calls clock_gettime() every couple of milliseconds and we've seen the bug twice so far this year. Good luck reproducing it. As you can see in bug 172907, Dave Jones had trouble reproducing it, and therefore thought the problem had been fixed, when in fact it hadn't. I've tried to reproduce using the program attached to bug 172907 without success. If I find a reproduction scenario I'll let you know. The patch is simple, has been signed off upstream, and I'm confident it fixes the problem.
