Pretty interesting indeed. One option would be to remove
the sys files before acquiring the lock. But I wonder
if this could lead to other issues.


Ping? Seems this thing got lost.

What if we move

rtc_sysfs_del_device(rtc);

before acquiring the lock?

Trying it now, I'll leave it going for a week and see if it reproduces.

Look good, thanks!


Thanks,
Sasha
