firewire, reboot, /dev/sda1 is not a valid block device

[Brian Clark <brian+nevdull@unwell.org>]

Hi Debian users,

My workstation's inputs (keyboard and mouse) froze today for the second
time in 6 years and I had to hit the reset button.

Everything came back up fine (thanks, journaling!) but when I try to
mount my external firewire drive which I use for backup, I get this:

~# mount /fwbackup
mount: /dev/sda1 is not a valid block device

~# grep fwbackup /etc/fstab
/dev/sda1       /fwbackup       ext3    rw,user,noauto  0       0

I've unplugged the firewire cable and plugged it back in, in hopes I
would see it be detected and 'enabled' in /var/log/messages or the
kern.log, but I only see this in kern.log:

Dec 20 13:14:53 localhost kernel: ieee1394: Node changed: 0-01:1023 -> 0-00:1023

Dec 20 13:14:56 localhost kernel: ieee1394: Node changed: 0-00:1023 -> 0-01:1023

And `mount /fwbackup` still doesn't like it.

Can someone put me on the path to getting this fixed?

Thanks for reading!
