Kernel panic: Fatal exception ---- The kernel was rebuild to include the megaraid2 driver patch to get rid of scsi errors (driver and firmware going out of sync). Version-Release number of selected component (if applicable): kernel .435 How reproducible: Didn't try Steps to Reproduce: 1. tpc-c run with swapping turned off 2. 3. Additional info:
Please reproduce this bug with the release candidate kernel that is not custom built. http://people.redhat.com/~lwoodman/.for_oracle/kernel-hugemem-2.4.21-2.EL.i686.rpm Thanks, Larry Woodman
There is a megaraid2 patch in bugzilla 102333. We want to try the kernel on the Dell system and need this patch. Either a custom build kernel with this driver patch, or an updated driver with this patch that will work with this release candidate. Van
Because the backtrace is seemingly nonsensical, i.e., no linkage to kmem_cache_reap(), there's nothing to work with. Please try the following debug kernel, which has the megaraid2 patch from BZ #102333 applied: http://people.redhat.com/~anderson/.for_oracle/kernel-hugemem-2.4.21-3.EL.md2.i686.rpm
Suhua, is this still a problem with the latest RHEL3 kernel or can we close the bug now? Larry
Suhua, we need to close this bug if it is no longer a problem. Can you verify that it is fixed in RHEL3-U4/ Larry Woodman
Closing due to lack of response.
