Ahoj,
To vypada ze je problem s filesystemem na md1, zkus znovu nabootovat z CD a pripojit ho nekam do adresare `mount /dev/md1 /mnt/nekam` a podivej se co obsahuje.
Souborovy system na md1 vypada dobre.

No, ted me jeste napadlo, co mas v grubu jako root device zkus tam dopsat (klavesa e) root=/dev/md1
To tam mam.

initrd /boot/initrd-2.6.27.7-9-pae
Tak to uz zbyva snad jen to ze by jsi v initrd nemel podporu pro raid, zkus ho znovu vytvorit a pridat tam potrebne moduly. Uz si nepamatuji jaky je na to v opensuse prikaz mkinitrd nebo tak nejak, ale bude to trochu slozitejsi. Nabootuj z cd udelej adresar treba /mnt/md1, pripoj do nej /dev/md1 a potom pomoc mount -o bind pripoj adresare /dev /proc a /sys do adresaru v /mnt/md1 (mount -o bind /proc /mnt/md1/proc) a nakonec udelej chroot /mnt/md1 . Tim se dostanes do systemu na md1 a muzes si zacit hrat s initrd.
ps. K cemu potrebujes pae? Mas vic jak 3GB RAM na 32bit masine?
To take nepomohlo. V initrd podpora pro raid je.

Vsiml jsem si, ze disky jsou docela velke. Nemuze mit system problem s nactenim initrd? Mel jsem nedavno podobny problem na HPw9400 (asi) s 300MB disky a byl to urcite problem BIOS a grubu. Zkuste dat adresar /boot na misto swapu a samozrejme upravit podle toho grub i fstab. Nevnucuji vam toto reseni, samozrejme cokoli, kde adresar /boot je na prvnich cylindrech disku by mohlo stacit.
Samozrejme misto 300MB melo byt 300GB 
Zkousel jsem konfiguraci zmenit takhle:
sda1 swap
sdb1 /boot
md1 (sda2,sdb2) /
Ale to nijak nepomohlo
Teprve ted jsem si vsiml, ze kdyz za

$
napisu exit, dam enter tak bootovani pokracuje.
Ví někdo co s tím?
Takhle vypada /etc/fstab
/dev/md1 / ext3 acl,user_xattr 1 1 proc /proc proc defaults 0 0 sysfs /sys sysfs noauto 0 0 debugfs /sys/kernel/debug debugfs noauto 0 0 usbfs /proc/bus/usb usbfs noauto 0 0 devpts /dev/pts devpts mode=0620,gid=5 0 0 /dev/md0 swap swap defaults 0 0
/dev/md1 / ext3 defaults,acl,user_xattr 1 1Jeste muzes zkusit konec prepsat na 0 0, pak se filesystem nebude kontrolovat pri startu, treba to pomuze odhalit pricinu problemu. Potom doporucuju vratit zpet na 1 1. Sice se ti system snazi sestavit pole sam od sebe, ale vetsinou jsem videl ze je potreba jadru predat parametry: "md=0,/dev/sda1,/dev/sdb1 md=1,/dev/sda2,/dev/sdb2". Alespon v archu to tak musim napsat. Zdenek
Vypis logu po nabootovani.
