What was the previous kernel which worked for you?
It worke with the kernel I had installed before: kernel-desktop-2.6.34.7-0.4.1.x86_64.rpm I will now install this kernel again in parallel and run a test to be sure the connection works.

Hmm, this is quite strange, as the main updates between 0.4 and 0.5 are xen changes and one isdn patch. Could you attach lsmod output? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It _IS_ working with 2.6.34.7-0.5-desktop again. After the update it did not work even though I rebooted a few times and it did not work. I have NOT installed any updates since than, I only installed 2.6.34.7-0.4-desktop additional. I will reopen if I can reproduce reliable. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
