After an entire day loosing my patience with an "up-grade" from version 10.0 to the 10.1 in a x86_64 machine I actually also detected the problem!
I had to make a reinstall.
It make me loose a lot of time. But it was worthy.
Also for those that might be interested and this is something even I have a hard time explaining to myself
it is possible to upgrade the kernel of 10.0 directly to the new 10.1 126.96.36.199-4 smp.
Just download the kernel 188.8.131.52-4-smp.rpm from a suse mirror (inst-source dir) near you.
At least in my server it did not afect nothing. Works like a charm!
Just the subfs stops working and the mounts for dvd's floppys and usb falsh drives must be made manually and of course some small changes to the /etc/fstab must be made. Which, for a server, it is actually a really good thing!
