Description Chris Ricker 2004-11-23 18:57:49 EST
I just upgraded a Dell PowerEdge 1600SC running FC2 to FC3. The
upgrade crashed and burned with a kernel panic in the reboot after the

The problem is that this machine has a megaraid card. In FC2, that
used the megaraid driver. In FC3, that uses the megaraid_mbox driver.
Anaconda didn't fix /etc/modprobe.conf accordingly, so the initrd that
was generated lacked the required megaraid_mbox driver. Fixing
modprobe.conf from rescue mode and regenerating the initrd fixed the

This will likely bite anyone upgrading < FC3 to FC3 with megaraid devices

megaraid2       SCSI    megaraid_mbox
megaraid        SCSI    megaraid_mbox

is in the upgrade list.

Is your card in the PCI listing for megaraid_mbox?
Comment 2 Chris Ricker 2004-11-28 18:31:12 EST
I think so. It's

01:02.0 Class 0104: 101e:1960 (rev 02)
        Subsystem: 1028:0475
        Flags: bus master, medium devsel, latency 32, IRQ 185
        Memory at fcd00000 (32-bit, prefetchable) [size=64K]
        Expansion ROM at fce00000 [disabled] [size=64K]
        Capabilities: [80] Power Management version 2

which should match

alias:          pci:v0000101Ed00001960sv00001028sd00000475bc*sc*i*

Hey, when did the kernel stop running the module upgrade program?

Chris, does running 'module_upgrade' by hand fix it?
Comment 4 Chris Ricker 2004-11-29 12:16:11 EST
Yep. I changed /etc/modprobe.conf back to the old entry

alias scsi_hostadapter2 megaraid

ran module_upgrade, and it corrected it to

alias scsi_hostadapter2 megaraid_mbox

There's no module_upgrade anywhere in the RPM %post scripts for the
kernel that's on that box (kernel-smp-2.6.9-1.681_FC3)
