Hello,
I cannot explain why the mount command issues with a segmentation
fault.
Kernel messages indicates

registered: "cd"

Kernel version and box features could help....

Please reproduce with devfs=nomount and send in that oops instead,
thanks.

Hello,
please aplogies. I have an Athlon 800, with kernel 2.4.8 (Mandrake 8.1). It seems that the message is very similar after rebooting with devfs=nomount, but maybe I am wrong.
