.config file for 3.4.0 kernel with the debug options used.
Acer Aspire 7750G laptop
Core i7/6GB
Slackware64 13.37 + 3.4.0-rc1 kernel built with kmemcheck & other debug options
Since 3.4.0-rc1, my laptop doesn't boot further than ACPI table parsing.
I cannot event get the dmesg output since the kernel hangs very soon. However,
the last visible lines are looking like that (copied from a working 3.3.0
kernel dmesg output):
ACPI: Executed 1 blocks of module-level executable AML code
[Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored
ACPI: SSDT 00000000af670718 0067C (v01 PmRef Cpu0Cst 00003001 INTL 20100121)

*** hang here, and sometimes I get a stack trace I cannot write here as it's
scrolled ***
I append my .config file to show what debug options I used.
3.4.0-rc2 doesn't work either.
