That's probably why the device isn't there for some time. The current "udev integration" of device-mapper seems very fragile. We see these failures and reports everywhere. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Weird effect that breaks boot.crypto. Factory, kernel-desktop-2.6.34-8.2.i586, udev-154-1.1
Would you test my package (device-mapper and lvm2) in Base:System/openSUSE_Factory ? I've verified it with openSUSE 11.3 M7 myself.

Thanks. Just submitted into Factory, and close this as fixed. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
