2.6.10-rc3-bk13 oops removing ide-scsi
From: Eyal Lebedinsky
Date: Wed Dec 22 2004 - 05:12:12 EST
I executed
modprobe -r st
modprobe -r sg
modprobe -r ide-scsi
when I got an oops and the machine froze up. Attached is the console
as captured serially.
The ide errors relate to an attempt to sccess /dev/hdc which was at the
time taken over by ide-scsi.
Here is the final part:
=======================
Unable to handle kernel NULL pointer dereference at virtual address 0000024c
printing eip:
f90e1466
*pde = 00000000

** PCI interrupts are no longer routed automatically. If this
** causes a device to stop working, it is probably because the
** driver failed to call pci_enable_device(). As a temporary
** workaround, the "pci=routeirq" argument restores the old
** behavior. If this argument makes the device work again,
** please email the output of "lspci" to bjorn.helgaas@xxxxxx
