Summary: System dead after resuming from S3, but not when docked
Product: ACPI
Version: 2.5
KernelVersion: 2.6.24
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Latest working kernel version: 2.6.23
Earliest failing kernel version: 2.6.24
Distribution: Archlinux
Hardware Environment: Dell Precision M20 (almost the same as Dell Latitude
D610), Pentium M 2.13, Sonoma i915, ati radeon x300 (using radeon driver)
Software Environment:
Problem Description: System suspends properly after echo "mem" >
/sys/power/state. After pressing the power button again, hardware wakes up but
the system is not responding and neither the kernel magic keys work nor the LCD
backlight. Dead. However if I suspend while being docked (dock module loaded)
and then resume (still docked) it surprisingly will resume just fine. Tried
many times and it just works that way. Please note that suspending when
undocked and resuming when undocked and the vice versa will not work.
2.6.23 worked without any problems, in all the situations described above.
Steps to reproduce:
As descirbed.
