Re: iBook2 doesn't resume properly after sleep
In-reply-to: <20040401102152.GA1577@osiris>
I have also recently had a persistent problem resuming my iBook2 after
sleep. The problem came with one of the upgrade to 2.6.8 and has
continued into 2.6.9. As reported by the previous people, the system
must be rebooted. Not only doesn't it resume X, but you cannot switch
consoles. I haven't tested whether ethernet access is enabled.
I suspected X when the system also froze after logout, when it recycled
gdm. However, the sleep problem happens just the same when X is not
running (/etc/init.d/gdm stop).
Under 2.6.8, when resuming it shows the usual text screen and gets this far:
aty128fb: resumed!
enable_irq(27) unbalanced
enable_irq(28) unbalanced
eth0: resuming
PHY ID: 4061e4, addr: 0
eth0: Link is up [etc]
eth0: Pause is disabled
That's as far as it gets. Somewhere during that sequence, it starts
fiddling with the cdrom. That might be significant, because someone else
reported that their problem went away when they stopped running
wmcdplay. I'll note that on my system, it finds the cdrom fine as hdb,
but udev neglects to provde the /dev/cdrom link. So something might be
up. However, I get the same error when I manually insert the cdrom
symlink (which is what I need to do (each boot) to use my cd/dvd drive).
Under 2.6.9, the text is slightly different, including an interesting
bit on going to sleep.
usbhid 2-1:1.0: resume is unsafe! [1]
ohci_hcd 0001:10:18.0: unlink after no-IRQ? Different ACPI or APIC
settings may help.
eth0: suspending.... [same as 2.6.8]
cpufreq: resume failed to assert current frequency is what timing
core thinks it is
aty128fb: resumed! [matches 2.6.8 from here on]
I presume the cpufreq message is because it doesn't load the cpufreq
modules. Don't know why. I also have to manually modprobe the sound
modules.
Before I file a bug report, does this info help anyone pin down WHERE
the problem is? (Kernel? Udev? User? CPUfreq?) I'm not currently
subscribed, but I'll check the web.
