This is after it boots up from a suspend.

what is the most recent kernel where this worked? Does setting CONFIG_HPET_TIMER=n in the .config help? I've tested 2.6.21-rc5, and things have improved. Resume works fine, but suspend still has some problems: After I do 'echo "disk" > /sys/power/state', it switches to a console mode, but displays no text. The hard drive appears to be working. When it is done, it sits at the console with no text. As soon as I hit any key (not just send an ACPI event), the system powers down. If I hit a key while it is suspending, nothing happens and it will still hang. It resumes fine. This happens whether I suspend from X or the console. Let me know if you need any logs or anything. Setting CONFIG_HPET_TIMER=n or CONFIG_NO_HZ=n does not change anything. killall klogd before attempting to suspend so you can see _where_ it hangs. Following Pavel's advice and killing klog, I get the following messages as it suspends to disk (this is all typed, so bear with me). <lots of 'ACPI: PCI Interrupt..."> <saving image data pages> Wrote 292760 kbytes in 16.81 seconds (17.41 MB/s) S| Disabling non-boot CPUs ...

patch 2.6.21-rc5 -> commit d459094083c3a23b31514bbe31cc3f4c21ed4445
Current git contains a patch that might be related to your problem.
This patch updates the kernel sources from 2.6.21-rc5 to the latest -git tree
(that will become 2.6.21-rc6).
Does it help?
That git patch fixes things. Screen is still blank while it suspends (unless I kill klogd), but I'm not sure if that's what its supposed to do. It turns off normally though. Reply-To: pavel@ucw.cz > That git patch fixes things. > Screen is still blank while it suspends (unless I kill klogd), That is expected behaviour. Can you close the report? Pavel |
Most recent kernel where this bug did *NOT* occur: 2.6.20.3 Distribution: Fedora Core 6 Hardware Environment: MacBook Core Duo Problem Description: When I suspend the machine to disk (echo "disk" > /sys/power/state), the system hangs after the following messages on the console: Stopping tasks ... done Shrinking memory... done (11627 pages freed) Freed 46508 kbytes in 0.26 seconds (178.81 MB/s) Suspending console(s) It hangs here. Interestingly, sending hitting the power button 3 times will wake it up. After that, it suspends normally. On restore, it hangs after "Suspending console(s)", and only wakes up after 3 power button presses. Unfortunately, it then handles those events and shuts down. Attached is the output of `dmesg -s64000` and acpidump. Steps to reproduce:
