Ah, this one is a Mac; if it's using the EFI to boot (I think it is) probably the BIOS on the card is not run; s2ram uses vbetool during resume, which may post the card BIOS. So I guess the card is not fully initialized (or it's just in an "unexpected" state) when radeonhd starts poking at it right after a cold boot.
ah, a good hint. Actually I'm booting not directly from EFI but via rEFIt and grub and such should have some legacy BIOS services but playing with vbetool on a freshly booted machine might reveal something.
no ... "vbetool post" actually reset's the machine, "vbetool vbestate save > outfile ; vbetool vbestate restore < outfile" does not change anything either but as before, a plain "s2ram -f" (the "-f" here used to keep it from using any hacks that just break it for me) works to get proper DDC output afterwards. -- with kind regards (mit freundlichem Grinsen), Ruediger Oertel (ro@novell.com,ro@suse.de,bugfinder@t-online.de) ---------------------------------------------------------------------- Linux Fatou 2.6.22.5-31-default #1 SMP 2007/09/21 22:29:00 UTC x86_64 Key fingerprint = 17DC 6553 86A7 384B 53C5 CA5C 3CE4 F2E7 23F2 B417 SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg)
