I have some experience to share on this subject: My colleague had a Macbook Pro with the Core Duo (not Core 2 Duo) for a while and he installed Kororaa (~gentoo++) on it (from the then current live CD - this was about 9 months ago). Without any kernel recompilation and it succeeded in suspending to disk - I doubt he ever did more than a handful of cycles. Like you, I've used suspend2 successfully for many years on other laptops so I was very optimistic in getting it to work on my MBP C2D when I got it, but it has proved a challenge: With a fair bit of fiddling I can often get it to suspend to disk for about a week's worth of cycles (~10 in my case), but then I typically get some kind of crash from fglrx causes suspend2 to hang on the way down to suspend. Also, the only way to have reliable resume is to reset the NVRAM on EVERY resume as well as before the initial bootup - without it, resuming will complain about mismatched memory sizes (it something to that effect). At the moment I use suspend to ram instead as when fglrx fails I at least get the chance to have a decent reboot rather then a crash - and it is of course significantly faster. Sadly, it isn't more stable - my worst experience so far is that it refused to wake up at all a few days ago - the power led refused to pulse, it just lit when the lid was closed and darkened when it was open. I had to use force power off. > So far I've > gotten the best results with userspace software suspend. My Macbook is > whitelisted, so in theory it should "just work".

Well, we have different hw so don't get your hopes too high, but for w few cycles I usually can get suspend2 to work as outlined here: http://www.xms.se/~zap/linux/macbookprocore2duo.html I'll happily provide more details if needed. > I'm running Debian Etch stable with mactel-patched 2.6.22-rc6 kernel. As mentioned on my page, I currently run 2.6.22-r5-mactel with Ortwin's config: http://www.odi.ch/prog/macbookpro/ 100% stable suspend2 (or lacking that, 100% stable suspend to ram) is at the top of my personal wish list. The iffy battery time isn't a priority to me since a typically can get plugged in and ndiswrapper works fine these days. High speed fans are annoying, but I can live with it. So second on my list is probably stable ACPI reporting of battery state - mine currently reads: # cat /proc/acpi/battery/BAT0/info present: yes design capacity: 0 mWh last full capacity: 0 mWh battery technology: rechargeable design voltage: 0 mV design capacity warning: 250 mWh design capacity low: 100 mWh capacity granularity 1: 10 mWh capacity granularity 2: 10 mWh model number: serial number: battery type: OEM info: Occasionally it works for a long time. but this is after just over 10 hours of use since last reboot. > Have any of you managed to hibernate (and resume) any Macbook / Macbook > Pro successfully?

Nor would I, but the reality is that I've never had a real problem on the MBP, ext3 has always saved my bacon. And (due to the above) I've typically crashed at least once a week for the last 6 months... / Jonas -- Jonas Petersson | XMS Penvision | mailto:[EMAIL PROTECTED] Box 3294, Västgötegatan 13, S-600 03 Norrköping | www.penvision.se Tel: +46 11 400 13 00 | Dir: +46 11 400 13 05 | Fax: +46 11 10 30 50 ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
