-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Running Toshiba Portege 4000, I have intermittent lockups at resume from STR. Those lockups were less frequent before 2.6.18 ("it mostly works"); after switching to 2.6.18 it is rather "it almost never works". After enabling full console output (SysRq-9) and doing suspend/resume I got:
BUG: lock held at task exit time! echo/1931 is exiting with locks still held! 1 lock held by by echo/1931 #0 (acpi_gbl_hardware_lock) {+...}, at [<c01df0d8>] acpi_os_acquire_lock+0x8/0xa
I also have relatively bad photo of screen with stack trace but it is not actually interesting (it just says task was exiting).
After that system stays still, I only can press power button.
echo mentioned above is likely to be
FILE=/sys/power/state PARAM=mem
/usr/share/suspend-scripts/run_scripts $debug suspend s3
if ! (/bin/echo $PARAM > $FILE &) ;then ret=1 fi
I appreciate any hint how to further debug the issue.
TIA
