Not sure which mailing list to post this to so going to both users and 

I have dapper running in a VM on VMware 5.5, breezy as a host. All of 
the recent Dapper upgrades have gone quite nice thus far, with one 
exception. When performing the upgrade of linux-image-386( to and linux-restricted-modules-386( to, the 
VM dies. By this i mean that, upon reboot, Grub comes up, the system 
starts to boot (the new "handdrawn" usplash comes up), and it gets as 
far a "Mounting the root file system" After a few seconds here, I get 
dropped to a console saying:
  Alert! /dev/sda1/ does not exist. Dropping you to a shell!

however, i do not get dropped to a shell and the VM just sits there, 

Luckily I make snap shots for just this purpose and can get back to 
right before the upgrade in seconds. I have confirmed that its only 
these 2 packages that cause this.

Not being a kernel "expert", or even a "the way ubuntu boots" expert, I 
am sort of stuck. Its obvious to me either the VM SCSI device is not 
being detected, or, if it is, its not being used at all. With not shell 
do goto i cannot diagnose the problem further.

Since dapper is a developemt work, and I'm running this in a VM, this 
is no big deal for me. I can just ignore that update for a while. I was 
jsut wondering if anyone else had the same problem/a fix/an answer.

Thanks and keep up the great work.
