Hello,

today I got the following oops with 2.1.131-ac10 SMP:

Unable to handle kernel paging request at virtual address 3b297367

Furthermore the system did lock up several times. With 2.1.131-ac10 I could
get some infos using magic-sysrq. The EIP values were c88341a1 and c88341a8.

Some output from ksyms:

c8836000 (6k) [ne]
c883604c ne_probe [ne]
c8833000 (6k) [8390]
c883304c ei_open [8390]
c8833ee8 ethdev_init [8390]
c8833498 ei_interrupt [8390]
c8833f54 NS8390_init [8390]
c8834708 NS8390_module [8390]
c883308c ei_close [8390]

If you need further informations please let me know.

Regards,

Jogi

    Well, yeah ... I suppose there's no point in getting greedy, is there?
