Hi. 32 bit on a laptop with intel graphics hardware.
Just had a kernel panic when resuming from a suspend to RAM using the new 2.6.38. First problem with suspend on this computer in nearly three years.
Right now I have some work to do so back to the last 2.6.37 kernel. I'll give some more info later. |

My Toshiba NB205 netbook with Intel GM945 is suspending and resuming correctly (but Desktop Effects don't work).

with 2.6.38-0.slh.2-aptosid-686 I get a different problem with resuming. After resume, I see the screen saver and the unlock dialog for around three seconds, and then the machine locks up (three times successively so it's reproducible). I can't get any reaction so I force the machine to power down.
I have Intel GM965. The power supply is connected while I do this.
I don't know where to find log messages that may help. dmesg seems to have nothing useful, same with pm-suspend.log |

| Resuming from a suspend to disk (hibernate) works, unlike resuming from RAM. |

| That is actually a quite rare combination, as suspend to disk is usually more likely to be affected... However at this moment, nothing really strikes out (an ICH6/ i945GME systems suspends and wakes up fine for me, although I rarely use suspend). The big problem with suspend related issues is how tightly these issues are coupled to the hardware and the running BIOS implementation, which are mostly hard to reproduce and debug. |

| BIOS update made no difference. What logfiles may be helpful? |

I dropped down to init 3 and did a pm-suspend.
On resume, the console had errors and a kernel panic.
They look like dmesg errors, time stamps like 90.773041 bad_area_nosemaphore messages.
But upon reboot, I couldn't see where these message may be. |

still kernel panics, although now I get a flashing LED to accompany the crash. |
