Subject: 2.4.20rc2: sunrpc oops in xdr_decode_string_inplace()
Date: 22 Nov 2002 07:16:12 -0800 [thread overview]
Message-ID: <87hee9vdmr.fsf@ceramic.fifi.org> (raw)
Has anyone seen this oops?
Spotted on sparc32.
Phil.
ksymoops 2.4.5 on sparc 2.4.20-rc2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-rc2/ (default)
-m /boot/System.map-2.4.20-rc2 (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.
