No wake up after suspend. - Toshiba L300
Last modified: 2009-03-17 09:59:20 UTC
Latest working kernel version:22.214.171.124
Earliest failing kernel version:126.96.36.199
Hardware Environment:Toshiba L300
Problem Description: Machine will not resume after suspending to ram. It wakes up but screen is blank and it halts (even capslock doesn't work). It depends on changes made from 188.8.131.52 to 184.108.40.206 in /drivers/acpi/sleep/main.c procedure:
+ /* If ACPI is not enabled by the BIOS, we need to enable it here. */
Steps to reproduce: Sleep and wake up.
it seems that we need to blacklist this Toshiba machine as well.
please attach the dmidecode output.
do you think this is a duplicate of bug #12038?
