Subject: 2.4.17: kswap crash in prune_dcache()
Date: 5 Feb 2002 20:57:16 -0800 [thread overview]
Message-ID: <a3qd3c$2jk$1@cesium.transmeta.com> (raw)
Additional information at:
http://userweb.kernel.org/~hpa/kswap/
After this event the machine was dead to userland, but still answered
pings.
2.4.17 SMP PAE kernel, modules disabled.
-hpa
ksymoops 2.4.1 on i686 2.4.17. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.17/ (default)
-m /boot/System.map-2.4.17 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
