Do you even know if this special case is applicable outside of Dell ICH5 boxes? And I thought your previous messages were referring to ICH6?


Every laptop I have access to, whether it's SATA or PATA, fires an ACPI notification when a drive is removed from a bay. The ICH5 case is probably somewhat special-cased, but when we move over to driving PATA with libata it's going to be a lot more useful. If ICH6 can be managed without resorting to ACPI, it's less necessary in the short term, but I think PATA support is going to require it in the end anyway (especially since we probably want to call the _GTM and _STM methods on PATA devices)

Yes, I do agree with this WRT PATA. Randy Dunlap's ACPI stuff is particularly interesting for this, though I haven't had time to review it in depth.

I'm a bit more reluctant WRT SATA.
