Problems with sata disc on a sarge

[a_d@gmx.at (Albert Dengg)]

Hi

i'm using debian sarge on one computer with a asus a7v600x board
(via kt600 chipset) with a custom compiled 2.6.16 kernel (with suspend2
patch).
it worked perfectlly well till now, but since the primary harddisk
starts producing smart errors and dma timeouts i decided to replace it
with a new sata drive.
in the process i wanted to migrate the main data to a sw raid1 set with
the sata disc and the other ide disc in the machine
(md0: raid1 for /boot, md1: raid1 with a lvm2 volume group for / and other
important data, and a second lvm2 vg for other data on the sata disc).

the problem is the following:
when the kernel brings up the md devices, it only brings them up in
degraded mode with only the section on the ide disc active...also the
lvm volume group that is only on the sata disc does not come up...
if i later start the vg by hand it works and also if i hot re-add the
partiotions to the raid they sync to...until the next reboot..

does anybody have any ideas/solutions by what this problem is caused
(and no, the sata drive is not compiled as a module, it is in the
kernel, as well as the md driver)

tia

yours
