I'm running a Win7 VM over AHCI, rebooting quite frequently. Depending
on host system load, I'm facing a lot of sporadic boot failures (disk
not found), obviously in SeaBIOS. Could it be that some timeout in the
init code bites us here? AHCI_LINK_TIMEOUT or AHCI_RESET_TIMEOUT? Just a
guess, I haven't debugged this yet.
