Subject: [bisected] PS/2 keyboard and mouse dead on resume on Intel D845BG
Date: Sun, 7 Oct 2012 15:13:27 +0200 [thread overview]
Message-ID: <201210071513.27959.linux@rainbow-software.org> (raw)
Hello,
Intel D845BG board comes out of S3 with PS/2 keyboard and mouse completely
dead. The machine works otherwise (with USB keyboard or over network). When
rebooted in this state, the BIOS hangs with blank screen. I have the latest
BIOS installed (P08).
Old kernels worked. Bisection pointed to commit:
b6dacf63e9fb2e7a1369843d6cef332f76fca6a3
(ACPI: Unconditionally set SCI_EN on resume)
Commenting out this line in drivers/acpi/sleep.c:
acpi_write_bit_register(ACPI_BITREG_SCI_ENABLE, 1);
fixes the problem.
Any ideas why this breaks on this system?
