Public bug reported:
I have experienced a full system lockup, not even SysRq+REISUB could
reboot the system. In the kernel logs I noticed multiple
tcp_fastretrans_alert warnings and the upstream bug
(https://bugzilla.kernel.org/show_bug.cgi?id=195835,
https://bugzilla.kernel.org/show_bug.cgi?id=60779) seems to indicate
this may be the reason.
In the attached kernel log, the hang happened immediately before the
last reboot.
