Hi, I have 3 bug reports about a clockevent failure while halting the system (2.6.31.11 kernel). It exactly pinpoints to the line 262 which got changed with this patch merged to 2.6.31.10 (and also 2.6.32.3): [4406.986777] kernel BUG at kernel/time/clockevents.c:262! [4406.986777] invalid opcode: 0000 [#1] SMP [4406.986777] last sysfs file: /sysfs/module/ip_tables/initstate All 3 systems have Pentium 4 processors with different clock speeds. Here's a screenshot of the full stacktrace: http://bugs.pardus.org.tr/attachment.cgi?id=4820 and the relevant bugzilla report: http://bugzilla.kernel.org/show_bug.cgi?id=15073 Thanks, Ozan Caglayan Pardus Linux -- http://www.pardus.org.tr/eng -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
