This is on a 1.4 ghz athlon with 1.0 Gb of ram (1-4gb HighMem enabled) and 512 mb of swap. I was away from the computer at the time, but I suspect that it was as I had left it, that is, with the ram nearly filled with the cache and a few megabytes of swap used. The system was probably five hours into a six hour divxencoding with drip. The kernel is stock 2.5.1-pre1 with the 2.6.2 i2c and lm_sensors patches applied. Ksymoops output for the first oops is attached. More information is available upon request and please CC me because I am not on the list. Thanks. _________________________________________________ Andrew Ferguson http://owsla.cjb.net | andrew@owsla.cjb.net Tintin Webring: http://owsla.cjb.net/tintin/ring/ --=_6TrnltStXW4iwm Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="ksymoops.txt" ---- Ksymoops output ---- ksymoops 2.4.3 on i686 2.5.1-pre1.

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.
