Hi,

I have just compiled a new kernel (2.4.15) and get an Oops when unmounting
a XFS partition.
My last kernel was 2.4.15-pre7-xfs and worked fine. It was compiled with gcc-3.0.
Because of a problem with the Nvidia driver (which doesn`t compile right with gcc-3.0)
I made an update to 2.4.15 and compiled everything with egcs again.

Processor: Athlon
Chipset:   Via KT-266A
Drives:    2x Maxtor IDE

This is, what ksymoops says:

ksymoops 2.4.3 on i686 2.4.15-xfs.  Options used
      -V (default)
      -k /proc/ksyms (default)
      -l /proc/modules (default)
      -o /lib/modules/2.4.15-xfs/ (default)
      -m /System.map (specified)

I hope, this is information enough.
I dont't know much about kernel bug tracking, so please tell me, if you need
more information.

Bye, Ralf
