Something similar, or the same thing, happened to me. 

I updated my system, and then on reboot it could not find the disk /dev/sda 
anymore. A pity, since it hold the boot and root file systems. I have a custom 
kernel, for various reasons, but now I could not get my custom kernel, of 
2.6.32 series, to work with the new udev features, and have no idea what it 
can be.

(The stock kernel does recognize the disks, but instead crashes on my radeon 
card, with or without the "fixes" described in the wiki. )

Without the /boot patition it was quite hard to get the system working again. 
Kernel update/downgrade does not work. I tried to downgrade packages, one 
after another, until I came to "udev", and after I downgraded it, the system 
worked normally. So now udev  is locked it in a downgraded state.

What is going on?
