Bug#901497: Hard system hangs after upgrade from 18.0.5-1 to 18.1.1-1

[Tehnic <tehnic@take3.ro>]

Hi all,

here some more informations. maybe it helps:

1) Purging flashplayer doesnt solve the problem

2) You still can login by network when graphic hangs

3) Xwayland process uses 100% CPU

4) Connecting to this process with strace shows only a lot of:

writev(16, [], 0)                       = 0

regulary interrupted by:

--- SIGALRM {si_signo=SIGALRM, si_code=SI_KERNEL} ---
rt_sigreturn({mask=[]})                 = 0

5) A restart/stop of gdm (systemctl restart/stop gdm) doesnt help,
you have to do a hard kill (kill -9) of the Xwayland process.

Regards. Robert
