RE: Help request on S3 resume problems

[Andreas Saur <saur@acmelabs.de>]

Hello,

same here! (nForce2 chipset).

After many many trial and error scenarios, I cannot remember exactly what I've done to get it work (resume from s3 on WOL) at least partitially.

1) In a sort of combination of using X86_UP_IOAPIC with USB turned off in BIOS, the system always woke up after sending the magic packet.
2) After turning on USB in BIOS the system woke up exactly 3 times. The forth time always led to a dead keyboard and a black screen, no ping.
3) Turning off X86_UP_IOAPIC in the kernel leads always to a dead keyboard and black screen, no ping.

Except WOL, S3 works fine here using the PowerButton or Keyboard.

I've studied all the the logs I've turned on in kernel, but there is nothing of interest concerning this error, at least for me.
Btw. It didn't make a difference whether doing the test in single user mode or not. Results were the same. I've also turned off all devices I could in the BIOS to minimize the IRQ impact. Didn't make a difference either.

It's a pitty, I was so close to a very cool MediaCenterPC for my living-room. But at the moment I ran out of ideas. If anybody is interested in my specs, can look into a bugzilla report I've posted earlier (another problem), the hardware didn't change, except the kernel. It's 2.6.17-rc3 at the moment. the last three mm patches led to kernel panics. (here my specs: http://bugzilla.kernel.org/show_bug.cgi?id=6326)

Regards,

Andreas
