Message-ID: <bug-217915-208809@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=217915
Bug ID: 217915
Summary: System fails to resume correctly after Thunderbolt
dock disconnected while sleeping
Product: Drivers
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: USB
Assignee: drivers_usb@kernel-bugs.kernel.org
Reporter: mark.blakeney@bullet-systems.net
Regression: No
After my comments on bug #216728, Mika Westerberg suggested I raise this new
bug.
I have a Dell XPS13 laptop and Dell WD19TB Thunderbolt dock and normally work
on two dock connected screens + keyboard + mouse with the laptop screen closed.
If my laptop suspends in this state, and I then unplug the dock (e.g. to take
the laptop away in the morning) then the screen stays blank when I try to
resume. This started when Arch Linux updated the kernel from 6.3.9 (good) to
6.4.1 (bad) and I have tested it bad with every point release of 6.4 since up
to 6.4.12 and is also bad on current 6.5.3. I have generally been using the LTS
kernel (currently 6.1.53) to avoid this bug.
If you wait about 60 to 70 secs then the screen does switch on. On 6.4 kernels
I had to wait about 2.5 mins, i.e. this delay has reduced on 6.5 kernels.
