Observation¶

Full medium test suites skip_registration and allmodules+allpatterns+registration fail sporadically for aarch64 in force_scheduled_tasks. The module is running in a loop:

read load dummy < /proc/loadavg  ; top -n1 -b| head -n30 ; test "${load/./}" -lt $limit && break ;

and is expected to be finished in 1005 seconds, but it times out.
In all failures spotted so far, the serial returned the same output at the moment of timeout

BTRFS info (device vda2): qgroup scan completed (inconsistency flag cleared)

so there could be some BTRFS inconsistency that is taking too long to be dealt with by the system.

As we cannot run proper performance tests and goal of the module is to improve stability of the tests.

allmodules+allpatterns+registration
