There have been many many threads about this, actually since the most recent kernel update in FC5 (kernel-2.6.18-1.2200.fc5), but certainly since FC6 too. This could be an upstream kernel issue (?). I don't think I've seen any definitive explanation or if it, or is being working on. But it seems that the newest kernels (specifically the ata_piix module) are now thinking that certain ATA chipsets (mostly from Dell, such as GX270's) also support SATA drives, when in fact your system doesn't. This may be in part because there was a unification of the SATA and ATA drivers (in the ata_piix module). Anyway, since it thinks your system supports SATA it then attempts to probe for all SATA drives, and since there are no drives and in fact no SATA bus, it has to wait for the SATA bus reset commands (SRST) to time out. Supposedly harmless, except for the insanely long boot times. That's my understanding of it anyway. -- Deron Meranda
