Kernel driver in use: pata_atiixp
Yet s(da) naming scheme is used.
Im unable to switch ahci mode off in BIOS(option does not exist).
Symptoms are 100% matching those matching what Gorgonzola wrote on 2009-04-06.
System freezes randomly on boot or on poweroff, at random times and up to
several freezes in row.
Sometimes I get dropped to busybox, because of rootfilesystem timeout.
Once X started, system is usable, but disk perfomance is extreme
sluggish, dd if=/dev/sda2 of=/dev/null bs=1GB count=1 reports average
speed of 10Mb/s....
Can someone point to some kind of temporary fix for this, please? :/
