Description Ian Wienand 2006-05-14 19:50:46 UTC
Most recent kernel where this bug did not occur: 2.6.16
Distribution: Debian
Hardware Environment: Dell X1 (ich6, i916 graphics, ipw2200 wireless)
Software Environment: 
Problem Description:

Laptop goes to sleep, but does not wake back up.  Does not respond to
ctrl-alt-del, so I figure is more than the screen being dead.  Ruled out about
the only thing I added, which was SDHCI driver for the SD card reader.  Also
happening with -rc3, everything working with 2.6.16.  Will attempt to bisect
further, but would be useful if anyone could confirm or deny.

Steps to reproduce:

Put laptop to memory sleep, will not wake back up.

Yes, binary search is very useful. I'd suspect some drivers are broken. try 
unload as many drivers as possible.

Do the LEDs indicate that the system made it successfully to sleep?
(eg. usually there is a slowly blinking amber led, or a moon or something
when the system is sleeping)

Do the LEDs then show that the wake event was recognized
and that it exited that sleep condition (eg. the moon goes out etc)?

Did suspend/resume work with 2.6.16 when in text mode? (eg. init 3).
If so, that would be a good comparison with 2.6.17, as the video
driver will be out of the picture.

ok, thanks I think I've tracked it down to sdhci.

I'll keep playing and update this bug
