Hi,
just checked again: there seems to be no update to the installed kernel:
Linux matrix 2.6.25.18-0.2-rt #1 SMP PREEMPT RT 2008-10-21 16:30:26 +0200 x86_64 x86_64 x86_64 GNU/Linux.
There seems to be two little problems, I grepped and searched around and found ‘puzzled pinguin’ as one of the extreme intellectual highlights…
and the log is full of:

Now this has been around for a while, posts regarding this exact one are older.
At Microsoft a fix takes a couple of months after I write a business case.
Should we at opensource not be ‘better’…
paleeeeeze…
this happens for all apps, here just pkglist; it is all on ext3, plain vanilla no gimmicks, no lvm.
thx
