Comment # 22 on bug 974627 from Dominique Leuenberger

Our current leads go very much in the same direction so far.

>From what we've seen, it is a race condition in some areas

while booting qemu-kvm with -smp 2,sockets=2,cores=1,threads=1 makes the
problem go away, using 8 cores and 16 threads shows it.

This icewm bug seems to be interesting for the case:
https://github.com/bbidulock/icewm/issues/37

Testing combinations / fixes is indeed time consuming, as no attempt done so
far revealed the issue inside a running system - we only ever seen this when
starting the installer directly of the media.

One of our next planned tests to confirm the theory with icewm is to create a
staging iso wirh icewm 1.3.8 (which, according to above bug report, did not yet
have the WM_NET_TIME code in it)
