Does any hardware work after resume, such as NIC, keyboard? So you think this is a recent regression. IS it possible you can try kernel between 2.6.12 and 2.6.15-rc7?
> So you think this is a recent regression. No no. I mean i tested two kernels and it's didn't worked with both of them. > Does any hardware work after resume, such as NIC, keyboard? NIC ??? After resume hdd make some thing like power test. CPU fun begin working with max speed (looks like ec is corrupted), normally min. On serial-console no output. VGA no output. Keyboard: i tryed ctrl+alt+del it's not working and alt+sysrq+b - some times rebooted some times not.
With kernel 2.6.14 is same issue. I tested with different bios options: ACPI version 2 (yes/no) Suspend Mode (auto/s1/s3) but didn't get positiv result.
With S1 it's generate falowing output with oops echo 1 ? > /proc/acpi/sleep Stopping tasks: ==========| [ACPI Debug] String: [0x04] "SIOS" ACPI: PCI interrupt for device 0000:04:00.0 disabled ACPI: PCI interrupt for device 0000:00:1d.7 disabled acpi_bus-0201 [02] bus_set_power : Device is not power manageable ACPI: PCI interrupt for device 0000:00:1d.3 disabled ACPI: PCI interrupt for device 0000:00:1d.2 disabled ACPI: PCI interrupt for device 0000:00:1d.1 disabled ACPI: PCI interrupt for device 0000:00:1d.0 disabled ACPI: PCI interrupt for device 0000:00:1b.0 disabled PM: Entering standby sleep hwsleep-0284 [03] enter_sleep_state : Entering sleep state [S1] Back to C!

It's looks like you have some thing chenget. Now It can wake if Xorg is on and CAN'T if init 1 with out x-server.
Comment #7 i'll report as separet bug.
One problem more after wake with x-server ewery thing working but NIC not working.
So only NIC can't work after resume, right? Could you please give me the 'lspci -vv' output after resume. Thanks!

Created attachment 6940 [details] lspci before sleep This is correct one
You are using MSI for NIC, right? I already sent a patch out for such issue. please try. http://marc.theaimsgroup.com/?l=linux-kernel&m=113642387900264&w=2
The patch is working. Thenks a lot.
With 2.6.15-mm3 is the same issue.
Resolved means we already have patch. If the patch goes base kernel, I'll mark it closed. This one could bemarked as resolved.
OK. Sorry.
Shaohua's patch in comment #15 shipped in Linux-2.6.17 closed.
