Subject2.1.72:(2.1.xx) OOPS on ifconfig of PCMCIA e-net card (8390)
From
Date


My Linksys PCMCIA ethernet card (8390) causes an Oops (and a crash)
when I ifconfig it.

I've been having this problem with all of the kernels I have tried in
the 2.1.x series (i.e most of 2.1.6x, 2.1.7x). I am using
pcmcia-cs-2.9.12.

Has anyone else seen this problem, or has anyone successfully used a
8390 based PCMCIA ethernet card with a recent kernel? Any ideas?

Below is the Oops from the 2.1.72 kernel (thanks to the serial console
support). Since ksymoops has problems with glibc, I ran it on a Sparc
(and, hence, have no disassembly). I've added comments about the
unresolved addresses (prefixed with "***").
