Just upgraded a poweredge 1850 server from Debian lenny to squeeze and can not boot with the new 2.6.32 kernel. >From lspci have this controller: SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 08) Running mdadm raid with root on md0. Normally run xen but all info is for when running without xen. I can still boot with the 2.6.26 kernel but not with the new 2.6.32 kernel. Under 2.6.32 it fails to start md0. in the busy box console Can see all the needed partitions. What was sda and sdb are now sdb and sdc that should not matter?? mdadm.conf is: DEVICE partitions CREATE owner=root group=disk mode=0660 auto=yes HOMEHOST <system> MAILADDR xxxxx@xxxxxxxxxxx ARRAY /dev/md0 level=raid1 num-devices=2 UUID=6f744c89:d2578f95:c150b018:d9f789b1 ARRAY /dev/md1 level=raid1 num-devices=2 UUID=7938d59c:28a69e5e:3facbdc2:12974557 raid1 mptbase mptscsih and mptspi module are loaded. Looks right but does not start md0. Any ideas?
