Earlier calculating pending signal for task was not done correctly. It has been fixed by below patch. http://help.lockergnome.com/linux/PATCH-__dequeue_signal-cleanup--ftopict368... Same code is first checked in to Linux 2.6.19 http://lxr.linux.no/#linux+v2.6.19/kernel/signal.c#L452 Above mentioned fix is not part of SLES10SP4. Reproducible: Always Steps to Reproduce: 1.Install SLES10 SP4 32 bit Operating System 2.Insert MegaRAID card and update latest driver and firmware. 3.Create a 4 span R10 VD with 2 drives in each span. 4.Mount the volume and start I/O 5.Assign 4 Global Hot Spare 5.Pull out a drive from each span. 6.Observe that the system hangs and crashes. 7.Firmware was still intact and rebuild gets kicked in there Actual Results: While I/O operations is in progress on VD, system hangs/crashes on removal of some drives of RAID volume. Expected Results: System should not hang/crash on removal of drives of RAID volume. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
