           Summary: blkext grabs hdd devices, stuff doesn't work
    Classification: openSUSE
           Product: openSUSE 11.2
           Version: Factory
          Platform: x86-64
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: P5 - None

After updating master kotd from
6580dd3e9ae59976b902a43cb1407cc863f22b9e
to
d2da64bc36fbbe03123416ec036321abbfa98daf
my machine got almost unusable.
$ cat /sys/block/sda/sda?/dev
259:1
259:2
259:3
259:4
259:5
259:6
259:7
259:8

it got exposed by
$ grep 259 /proc/devices 
259 blkext

suspend (and kernel/power/user.c) doesn't count with majors > 255.
lvm (lvm2-2.02.45-6.1) won't activate lvm until I change its proc conf to
something meaningless (/hole), since it ignores blkext entries otherwise.

Is this expected behaviour? Then userspace should be fixed.
If not, what could have caused this? I see nothing related in the kernel
changelog, so I doubt it's bound directly with the kernel update.
