Summary: resume after suspend-to-ram broken on Sony Vaio
VGN-SR19VN when sony-laptop driver present
Product: ACPI
Version: 2.5
Kernel Version: 2.6.30rc2
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Platform-Drivers
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
Hardware: Sony Vaio VGN-SR19VN
In 2.6.30rc2, resume after suspend-to-ram on a Vaio SR19VN with the sony-laptop
driver compiled into the kernel results immediately in a hard freeze: the
screen stays off/black and the system appears completely hung, e.g. pressing
Caps Lock does not cycle the keyboard LED.
Steps to reproduce:
1. Build kernel with ACPI and sony-laptop driver compiled in
(CONFIG_SONY_LAPTOP=y)
2. Boot with init=/bin/bash
3. Run s2ram -f -p to suspend
4. Attempt to resume as usual by pressing the power button.
If the kernel is built without sony-laptop, step (4) succeeds.
