Title:
LTP uevent01 will fail on GCP n2d-standard-64
Status in ubuntu-kernel-tests:
New
Status in linux package in Ubuntu:
Confirmed
Status in udev package in Ubuntu:
Confirmed
Bug description:
Because udev takes too long to release the loop device, LTP test
uevent01 (and some other tests) may warn about not being able to
detach the loop device. This is identified as a failure.
