I've spent a bit more with debugging this issue. Currently I know
followed:
1. Same happens without ToI using mainline hibernation
2. I've reproduced it once without nvidia proprietary module (using nv),
however it happens too rarely.
3. It hangs in infinite loop at drivers/acpi/hardware/hwsleep.c:
do {
status = acpi_get_register(ACPI_BITREG_WAKE_STATUS, &in_value);
if (ACPI_FAILURE(status)) {
return_ACPI_STATUS(status);
}
} while (!in_value);
(verified by adding printk())
This looks like hardware/bios bug, however there was no such problem in
times of 2.6.25 kernel (with and without nvidia proprietary module)
Hardware is MSI M673 laptop. Any ideas? Maybe some workaround? Bisecting
is too difficult and almost impossible.
