Description Elrond 2006-04-17 15:48:10 UTC

Have a problem of segmentation fault when I boot Fedora Core 5 with the last
kernel (x86_64), 
/etc/rc5.d/S05kudzu line 23....

How to solve it ?

Comment 1 Bill Nottingham 2006-04-17 17:39:18 UTC

Can you get a backtrace in gdb?

Comment 2 Elrond 2006-04-18 19:26:03 UTC

That's a bug with my creative Sound Blaster Audigy 2 Platinium EX, but I have
sound, I found this when i was reformat my FC5

When you get to that point, please type 'bt', and get the full trace.

Comment 8 Bill Nottingham 2006-04-20 15:43:29 UTC

Can you install the kudzu-debuginfo package available at:

http://download.fedora.redhat.com/pub/fedora/linux/core/5/x86_64/debug/kudzu-debuginfo-1.2.34.3-1.x86_64.rpm

and then repeat the steps? Either that stack trace is corrupted, or this is a
new bug.
