atari and LVM

["Christian T. Steigies" <cts@debian.org>]

Hi,
I have been able to boot my Atari/CT60 again, but I needed to boot (and load
hddriver) from floppy, since the harddisk partitions seems to have suffered
during the crash in September. Partitions are detected during boot:

[    2.850000] hda: SAMSUNG MP0402H, ATA DISK drive
[    3.580000] ide0 at 0xfff00000 on irq 15 (serialized)
[    3.610000] ide-gd driver 1.18
[    3.620000] hda: max request size: 1024KiB
[    4.080000] hda: 78242976 sectors (40060 MB) w/8192KiB Cache, CHS=16383/255/63
[    4.110000] hda: cache flushes supported
[    4.180000]  hda: AHDI hda1 hda2 hda3 XGM< hda4 hda5 hda6 >

But the partition table is not recognized. Nevertheless, it boots happily
from hda5, but the lvm partitions do not show up:

root@garkin:~>lvscan 
  inactive          '/dev/garkin/buildd-sid' [4.00 GiB] inherit
  inactive          '/dev/garkin/swap' [2.00 GiB] inherit
  inactive          '/dev/garkin/build' [10.00 GiB] inherit
  inactive          '/dev/garkin/sid-m68k-sbuild-3093f291-829f-4c52-9eb4-fb242fafdd8c' [4.00 GiB] inherit


After "lvchange -ay /dev/garkin" the partitions are active, but I still can
not mount them. Anybody have an idea?

This is one of Michael's kernels, I think have booted this before:
