Subject: Kernel Hangs, EIP is at scsi_decide_disposition
Our mandriva boxes are randomly crushing after
migration to 2006.0 download version. The same
hardware has had mandriva 10.0 withuptimes of over 230
days....but nowadays it is hardly a week before a
crash for over 6 nodes with latest kernels.
I captured one of our lockups and am attaching the
output of ksymoops for further interpretation by mroe
experienced eyes when it comes to kernel internals.
Here is the actual error, and attached, the ksymoops
interpretation of it.
Unable to handle kernel NULL pointer dereference at
virtual address 000002a9
printing eip:
