Hi friends
I have a problem loading the yenta_socket.ko under
"Linux winter-lnx 2.6.9-rc1 #1 Wed Sep 29 15:39:33 PDT
2004 i686 i686 i386 GNU/Linux". From dmesg outtput it
gave me an error like
" Unable to handle kernel NULL pointer dereference at
virtual address 00000008" Can anyone give me some
pointer on why I'm seeing this error?
Thanks in advance,
Todd Nguyen

Something for the PCI people to look at I think... However, you might
consider including _full_ lspci -vv information rather than just a

Hi Russell,
Here is the output for lspci -vv. I hope someone
out there can give me advice. Please let me know if
additional information I should post.
Thanks in advance,
