--- Comment #10 from freedesktop.org@nentwig.biz --- So, there's 4.19rc1-amd-next \o/
echo: write error: Device or resource busy
This started to happen with 4.18. dmesg:
[ 171.245467] Freezing of tasks failed after 20.006 seconds (1 tasks refusing to freeze, wq_busy=0): [ 171.245484] systemd-udevd D 0 700 615 0x80000124
So, is this sth. to report to fricking systemd to?
Gee, really...?!
