"sometimes it crashes." That implies multiple crashes. Could we see some of the other oops messages? This oops looks like we've got a return address on the stack that points at a "ud2a" undefined instruction --- ie. the middle of a BUG() call. That would imply that we should see other diagnostics about the bug just prior to the oops --- please include those. But EIP is pointing to totally bogus Code: (the 00 00 00 00 00 garbage is interpreted as "add %al,(%eax)" hence the oops dereferencing %eax). That implies that the real problem is elsewhere, possibly hardware. More info will be needed to take this further. After what seems like endless problems with this server, filesystem corruption, and rpm database corruption (disk blocks shared with other files on the filesystem!!!), the hardware has been replaced, and reinstalled and patched with the latest (hence running e.34smp). Feel free to close this bugzilla. If we run into future issues we'll open a new ticket. (The old hardware passes all hw diags, either dell, or memtest86). Thanks Kambiz OK, thanks for letting us know! |
