Hi, Thanks Pedja for you great email. In my case it's not a laptop but workstation, but anyway I have found that pci='nocrs' workaround works. (BTW, Another one we found is turning off AHCI in BIOS and leaving only ATA). So now I have pure kernel issue - Kernel doesn't see root partition. It gives me the list of available partition with sdaX and sdbX ones, but not trace of RAID/LVM (and I have root on RAID/LVM). I'm pretty sure I have compiled all necessary option to allow boot from /dev/main/root which is on LVM on /dev/md2. I guess that RAID is fine, cause kernel is booting from /dev/md1. Any ideas?
