Bug#358153: testing (etch): cannot boot on software raid

No. Additionally, dmesg displays something I'm not sure how to interpret:

ata1: SATA max UDMA/133 cmd 0x6800 ctl 0x6402 bmdma 0x5400 irq 74
ata2: SATA max UDMA/133 cmd 0x6000 ctl 0x5802 bmdma 0x5408 irq 74
ATA: abnormal status 0x7f on port 0x6807
ata1: disabling port
scsi0 : ata_piix
ATA: abnormal status 0x7f on port 0x6007
ata2: disabling port
scsi1 : ata_piix

> * if not was piix loaded? (cat /proc/modules)

Yes, loaded.

> * what was your cat /proc/cmdline

root=/dev/md0 ro

> * does cat /proc/mdstat show something when dropped in?

No (except from the usual "personalities: [raid1], unused devices:

> try to run the md boot script by hand:
> . ./conf/initramfs.conf
> . ./scripts/functions
> . ./scripts/local
> ./scripts/local-top/md

No errors (and no output).

> # check if /dev/md0 is there

Not there.

> mountroot

"/dev/md0 does not exist, dropping to a shell!"
