Bug 4058 – Powerbook sleep issue

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description David Rose 2002-06-23 11:32:34 UTC]

Putting the notebook to sleep more than once, when it wakes up the screen fails
to light up and the keyboard does not respond. Only recourse seems to be a hard
reset.

Powerbook Titanium II/G4 667mhz, kernel ppc-sources/linux-2.2.19-r5
pmud version appears cvs revision 1.1.1.1

Please upgrade to latest kernel release (r6) and re-confirm this issue

[Comment 2 David Rose 2002-06-24 12:02:34 UTC]

OOPS. I'm running ppc-sources/linux-2.4.19-r6, not -r5. Sorry. FWIW, pmud did
not work at all on -r5.

Heres what i've been able to come up with:

Sleep isn't supported on this machine yet because we don't have the
necessary informations to implement support for it in radeonfb for 
the M7 mobility chip.

If ATI ever manage to schedule some time to send us those infos
then we'll have sleep working fully on this model. In the meantime,
you'll unfortunately have to stick without sleep, or maybe hope
somebody will disassemble enough of the MacOS driver to figure out
what has to be done. The sleep code for the M6 definitely doesn't
work on the M7.

The benh kernel (2.4.20-pre4-ben0) seems to have solved this issue, though I
have not tested it much yet.
