post-2.6 upgrade problems

[Aaron Thoreson <aaront@midco.net>]

Hello,

I've seen this about, but not been able to find satisfactory resolution.

After an upgrade from 2.4.19 stable to 2.6.9 custom (maybe too 
ambitious?) I've lost the ability to ssh into the upgraded box.

auth.log is reporting
error: openpty: No such file or directory
error: session_pty_req: session 0 alloc failed

Now, I know with 2.6, devfs went the way of the dinosaur to be replaced 
by udev.  However, the udev I've got from backports.org conflicts with 
lvm2, so I can't install it.  My 2.6.9 kernel has /devfs support and 
auto-mount devfs both compiled in.

I've seen fixes ranging from lilo changes to kernel patches.  Been 
looking for a few days with only dead ends.  Can anyone provide a 
definitive answer to this for me once and for all? :)

Thanks a bunch!
