Summary: Suspend/resume fails with pm_test=processors
Product: ACPI
Version: 2.5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
Machine: Sony VAIO VPCSB2C5E
Processor: Intel(R) Core(TM) i5-2520M CPU
using pm-suspend with /sys/power/pm_test set to freezer,devices and platform
succeed even when repeating the test several times.
When set to "processors" the machine hangs, although I'm not sure if it hangs
during suspend or resume. Sysrqs keys does not work either after the hang.
After disabling all processors but cpu0 suspend worked reliably.
I'm available to do deeper debugging, if needed. Currently I don't know where
to start.
