Hello PA hackers,
I've tried various -rc candidates in the last few weeks, and sadly the
parisc kernel is in pretty bad shape.
At the beginning I started to get problems only when I had USB
keyboard/mouse attached to the PA machine. This lead to bugzilla
http://bugzilla.kernel.org/show_bug.cgi?id=11913
Now, with -rc4 and -rc5 things got even worse.
Crashes happen often just directly at the beginning.
I'm sure it's not USB related any more, and I assume we have some
strange mm-problem somewhere.
The kernel crashes at various places, and mostly a null-pointer is involved.
Right now I'm clueless...
Helge
PS: I'm happy that I just recently bought this one:
