There are bugillas about that part of the issue, I'll post the numbers later. This particular run has a "tainted" kernel, with the Nvidia driver, but I have older logs without the taint, so that's not the issue. And this report is against os-prober, anyway. The full syslog of the event is attached.

On a previous run, when I noticed this problem, I was running an update (yast online update, ie, mandatory packages), perhaps a hundred updates (this is a seldom used test partition). A particular rpm update hung for so long, that I had to kill it. -- 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.
