VFS: Cannot open root device «801» or unknown-block(8,1)

Dobrogo vreemni sutok!
(pardon za latinicu)

Est laptop Compaq Presario F756NR s nVidia chipom MCP67
Stavlyu Slack12 vse OK, sobirau yadro pod etot laptop no ne mogu zagruzit, vpadaem v paniku:

VFS: Cannot open root device "801" or unknown-block(8,1)

Hotya vse pravilno koren na sda1 tobish disk sata major 8, minor 1
Do vpadeniya v paniku chipset raspoznaetsya, podderzhka v yadro vkluchena, kak vpochem i SCSI.
Razdel pod ext3 i sootvetstvenno tozh vklucheno.
Sizhu 2 dnya, dumau chto pereproboval vse. Vkluchal/viklyuchal vse podryad, kak v modulyah tak i v yadro.
Proboval gruzit initrd yavno ukazivaya chego hochu:

mkinitrd -c -k 2.6.24.2 -m ext3 sata_nv -f ext3 -r /dev/sda1

Ne pomogaet, ne poluchaetsya smontirovat koren.
Slax, RescueDisk (pomoemu on na Gentoo), i Kubunta 7.10 gruzyatsya bez problemm.
Do etogo nastraival pohozhiy laptop na pohozhem chipe MCP51 problem ne bilo.

Budu priznatelen esli kto poskazhet kuda kopat, t.k. u menya uzhe prosto ruki opuskautsya.

Spasibo.
