Subject: PROBLEM: kernel bug, dcache.c:362
Date: Tue, 28 May 2002 16:37:40 -0700 [thread overview]
Message-ID: <20020528163740.A2607@uffda.sdsc.edu> (raw)
The problem: /var/log/messages reports a kernel bug at dcache.c:362,
an invalid operand. See the excerpt below.
The system is uffda.sdsc.edu, a Dell OptiPlex GX1 running Red Hat 7.3.
I installed it on May 7 (an upgrade from Windows NT). Since then,
I've installed XFree86-doc, AbiWord, fvwm2, nvi, openssh-server, and
Opera 6.0. I've also installed several updates from Red Hat Network,
including a kernel update from 2.4.18-3 to 2.4.18-4.
Prior to the occurrence of the bug, I had been able to connect to
the system using ssh. Afterwards, the system responded to ping, but
"ssh uffda" from a Solaris box hung indefinitely (i.e., until I killed
it with control-C).
I wasn't actively using the system at the time, and I know of no
significant processes that were running when the bug occurred.
I probably had several shells and xterms running, but they were idle.
About 11 hours after the bug occurred, I cycled power on uffda, and
it rebooted normally, other than some unsurprising messages about the
file system having been shut down uncleanly; I don't recall the exact
wording. I ran a file system check, and it didn't find any problems.
Please let me know if I can provide any more information.
