True.  I wanted to see if it was at all useful before flooding the list 
with details.  If you do want to know more, please tell me.

I was crashing the machine.  :)

I'm playing with "Xen" virtualization and a VM panicked and caused a 
reboot.  I booted back to vanilla 2.4.26 kernel to check the VM 
filesystems.  When I rebooted, it tried to mount the root partition and 
gave me that message/dump.  It didn't actually crash or panic the whole 
system at that point, it just couldn't perform the automatic repair and 
refused to remount the root fs r/w.   After getting the crash info from 
dmesg, I rebooted again, this time to 2.6.7, which did its "repair" and 
mount just fine.

I only barely caught the dump as it scrolled by during boot, so not 
really.  "dmesg" didn't show anything other than the dump data and the 
usual kernel boot messages.

It still mounted the root volume, just r/o.  Then I did "dmesg > 
/boot/xfs_dump".  /boot is on a different partition, but it's the only 
other partition.  I just don't have /usr, /var, etc on separate 
partitions in this case.  At least I didn't have to write it down by 
hand as at times in the past...

Yeah.  This isn't an especially important machine, so I'm in no great 
hurry.
