Subject: [2.6.22-rc3][ACPI?] Resume from s2r doesn't work.

Hi, resume from suspend to ram doesn't work for my laptop and never has. So, this is not a regression. Hibernate (aka suspend to disk) works, however. When I resume, everything seems to come up (fan becomes busy, disk and dvd spin up for a short time), but the machine is not responding to anything - neither keyboard, mouse nor ping from another machine. The laptop is effectively dead and only a power cycle helps. I've tried a minimal config and init=/bin/bash as well, but the result is the same. When I skip acpi_enter_sleep_state(): diff -urN -X b/Documentation/dontdiff a/drivers/acpi/hardware/hwsleep.c b/drivers/acpi/hardware/hwsleep.c --- a/drivers/acpi/hardware/hwsleep.c 2007-05-27 23:47:25.000000000 +0200 +++ b/drivers/acpi/hardware/hwsleep.c 2007-06-01 10:45:46.000000000 +0200 @@ -268,6 +268,7 @@ u32 in_value; acpi_status status; + return_ACPI_STATUS(AE_OK); ACPI_FUNCTION_TRACE(acpi_enter_sleep_state); if ((acpi_gbl_sleep_type_a > ACPI_SLEEP_TYPE_MAX) || my laptop suspends and immediately resumes without problems. So it seems, that the drivers suspend and resume correctly. Attached is my minimal config, /proc/cpuinfo, lspci -vvv and dmesg output. How can I go on from here? Anything I can test, patch or debug? Regards, Olaf.
