PROBLEM: kernel oops 2.6.20 (ubuntu feisty) when inserting compact flash card
From: Stef Epardaud
Date: Wed Feb 21 2007 - 05:27:39 EST
Hello,
I got an oops when inserting my compact flash card in my laptop.
The laptop is a Dell X1, using the builtin compact flash reader, which I
understand works through PCMCIA.
My kernel is stock ubuntu latest unstable: Linux version 2.6.20-8-386
(root@vernadsky) (gcc version 4.1.2 20070129 (prerelease) (Ubuntu
4.1.1-31ubuntu2)) #2 Tue Feb 13 05:15:43 UTC 2007
The oops:
