RE: recent udev upgrade failure on alpha

["Uwe Schindler" <uwe@thetaphi.de>]

Hi Bob,

I downgraded udev on this unstable machine by downloading and archiving the
old source package (which is still on the servers for "stable"). This works
for now.

My bigger problem is that recent kernels (even the stable one no longer work
for me). On mounting my root  xfs filesystem it produces a message about a
wrong relocation format / some other linking problem when loading the XFS
.ko (the exact message is not known, its somewhere in the screen buffer of
the already rebooted with older kernel machine, I can only remember what the
problem was - next time I try I will take a pen and write down the message
on console). This happens with the last stable kernel version, did not test
2.7.37-1 until now. 
The last kernel that works for me is 2.6.31-1-alpha-generic. Does anybody
knows what the problem loading the XFS module is?

Unstable is else still running fine!

Uwe
