Bug ID: 60569
Summary: Kernel panic after ACPI Exception
Product: ACPI
Version: 2.5
Kernel Version: 3.9.6-1-ARCH
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
Assignee: [email protected]
Reporter: [email protected]
Regression: No
About an hour after resuming from sleep today, after about 29 days of uptime, I
got a kernel panic. I remember ath9k in the stack trace (my WLAN controller).
Unfortunately I neglected to take a photo of the screen and so I have no record
of it. Since this happened after 29 days of uptime, during which the system
barely changed (I installed some rather high-level userland software), it will
probably be difficult to reproduce.
Looking at the logs, however, I see the following error messages, starting
right after resume (all messages in reverse order, as produced by journalctl
-r):
