https://bugzilla.novell.com/show_bug.cgi?id=334587#c5 Stefan Dirsch changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sndirsch@novell.com Status|NEW |RESOLVED Resolution| |FIXED --- Comment #5 from Stefan Dirsch 2007-11-27 15:02:27 MST --- Thanks. The patch seems to have been applied to 2.6.24_rc2_git6 we currently use for STABLE/Factory. Let's assume it's fixed for openSUSE 11.0 and kernel-of-the-day. Please reopen if the problem still occurs with kernel >= 2.6.24_rc2_git6. -- 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.

I'll check the 2.6.24 kernel nonetheless. -- 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.
