Ping. In
2.6.35 it became much worse. In 2.6.33 I had DVD as IDE and HD as PATA
which was OK. In 2.6.35 using exactly the same setup I lost any access
to HD. I.e. with these modules:
{pts/1}% lsmod | grep piix
ata_piix
22460 0
libata 193241 4
ata_generic,pata_acpi,ata_piix,ahci
piix 5408 1
ide_core 116373 3
ide_cd_mod,ide_pci_generic,piix
2.6.33 detects DVD as hda and HDD as
sda; with 2.6.35 only hda is detected. If I unload IDE stack and
reload ata_piix it correctly detects both HDD as sda and DVD as
sr0.
So without this patch dracut generates initrd that cannot find
root device.
Thank you!
