Re: suspend on hp nx7400
I forgot, I get a kernel crash if I don't unload ipw3945 driver before
suspend to disk. WIth suspend to ram it's not necessary.

That's not a suspend2 issue.
Vanilla kernel 2.6.17 has not the support for ahci sata controller
suspend and resume. Patched kernels like the ubuntu's one has patches
to make work suspend to disk (indifferently suspend1, uswsusp or
For suspend to ram to work you need 2.6.18.*-mm* or >2.6.19-rc*. I
have not seen patches to 2.6.17 that include ahci support for suspend
If you set in the bios the controller in standard mode, ata_piix
module will control it, and suspend to disk will work with 2.6.17
(using suspend2, uswsusp, or suspend1).
See my page http://emisca.altervista.org/nx7400 . I have wrote some
instructions to get a fully working linux system on that machine.
