Most of the hardware works fine, with the exception of suspend-to-ram.=20 I have a strong suspicion that the SATA controller is to blame for that, as I have tried every possible combination of s2ram parameters and still the display stays black upon resume, only the hard disk LED lights up and stays that way. I have seen suggestions to try the ahci driver instead of the ata_piix driver, however, as far as I understand this would need switching the controller mode in BIOS. The BIOS is, unfortunately, utterly crippled and gives almost no options to change anything beyond the system clock. Is this a known problem with ICH7? Can anybody give me some additional hints? Thanks in advance, Yours, Florian P.S. I would have tried a serial console, however, this is a so-called legacy free laptop and I currently don't really know how to get one. I'm planning to try a USB-Serial-Converter next. --=-bxkV75FnPXOeE4xMy6Ky Content-Type: application/pgp-signature; name=signature.asc Content-Description: Dies ist ein digital signierter Nachrichtenteil -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQBFxPe17CzyshGvatgRAttxAJ920Dzntxbj3mvCckdC6b/MazorywCeOKLC GncLakFsEIn+nTF+cIC2MkY= =cQek -----END PGP SIGNATURE----- --=-bxkV75FnPXOeE4xMy6Ky--
