Description:
On MacbookPro11,4 suspend breaks with kernel 4.19.8-arch1-1-ARCH. First time suspend work but any attempt to suspend after that will fail. I did not tweak that much on this machine so I don't think any additional config files and such really matter. I attached dmesg output, in which you'll see that usb2 is blocking suspending. I also added lsusb -v for that specific device, there is a small difference between pre and post suspend for port 4. Additional info: * linux 4.19.8.arch1-1 Steps to reproduce: On MacbookPro11,4: suspend, resume and suspend again. Works without gui and without even logging in. |
This task depends upon
I can't reproduce anymore since I handed in the MacbookPro11,4 and got a Dell now, which does not have this issue.
This is possibly related to the misbehaving SD card reader on usb2, which does not reappear after the first suspend.
The (so far fruitless) bug report and discussions of the card reader issue are here:
- https://bugzilla.kernel.org/show_bug.cgi?id=111201

Apparently with earlier kernel versions this just did not cause subsequent suspends to fail.
