The affected hard disk is mostly sdb (ata2) which hosts the root partition, but occasionally also sda (ata1) where /boot and /home reside. When booting without XEN, no such messages appear. -- 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.
