kernel panic +SysRq full console output
Hello, Juanjo. Can this problem be reproduced with an untainted kernel? Hi Ernie, I guess the kernel is tainted because the loading of HP's management modules (we are using "hprsm" and "hprsm" rpms provided by HP). As far as we don't know how to repoduce this problem, we will disable the HP management services and see if the serves panics again. Regards. Have you ever seen this problem before? How long was it running before the panic? It is the first time we see this problem. The server had an uptime of 34 days. Note that we are using HP management services on this server since 01/05/2005. OK, I don't think there's much we can do here without more information. It would be useful if you could enable netdump and capture a core file if the crash recurs, as otherwise there's not much to go on here. OK. I will try to configure netdump. We have recently found a problem in the RHEL-3 kernels which is likely to be the cause of this bug. Details are in bug 155289. We have a test kernel built which should resolve this problem; x86 rpms can be downloaded at http://people.redhat.com/~petrides/.pte_race/kernel-hugemem-2.4.21-32.4.EL.i686.rpm http://people.redhat.com/~petrides/.pte_race/kernel-hugemem-unsupported-2.4.21-32.4.EL.i686.rpm http://people.redhat.com/~petrides/.pte_race/kernel-smp-2.4.21-32.4.EL.i686.rpm http://people.redhat.com/~petrides/.pte_race/kernel-smp-unsupported-2.4.21-32.4.EL.i686.rpm http://people.redhat.com/~petrides/.pte_race/kernel-source-2.4.21-32.4.EL.i386.rpm and these patches will be in RHEL-3 U6. Given that you don't seem able to reproduce this, please let us know if you want to try these kernels or simply wait for U6. We are unable to reproduce this problem, so we will continue using the stable kernels and wait for U6, thanks for your interest. Regards. OK, I'll close the bug for now on the basis that we believe this problem will be fixed in the next release. Please reopen if you need to pursue this further before then. *** This bug has been marked as a duplicate of 155289 *** An advisory has been issued which should help the problem described in this bug report.
