I updated xfs cvs just now (1 March 23:30 GMT) and just after rebooting
kupdate segfaulted on me and resultet this attached Call Trace. I'm no
kernel expert and I don't know if this sayes much. I could probably get
more info about this if given the prober pointers. This is a up to date
Linux-Mandrake cooker system and the kernel was compiled with RH7.0
kgcc. I'm attaching my dmesg log as well.
