Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.21-ck3/ (default) -m /boot/System.map-2.4.21-ck3 (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.

Results may not be reliable. 2.4.21-ck1 was fine under nearly the same circumstances. I rebuilt with a newer -ck when I was configuring my new ADSL bridge to work with Linux pppoe, but I doubt that's related. Anyway, it drove my wireless card driver nuts too, probably due to some busted interrupts. It kept printing a SW TICK STUCK? message. I'll revert to vanilla for now. :( -Josh --=20 Using words to describe magic is like using a screwdriver to cut roast beef. -- Tom Robbins --sm4nu43k4a2Rpi4c Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQE/IL22T2bz5yevw+4RAnskAJ4ig0ZVaWkDoG9e3HK6TrkuFZlu0QCgqL84 CVxxE5Dne6jLEUP6/XKFB+A= =bVbi -----END PGP SIGNATURE----- --sm4nu43k4a2Rpi4c--
