Comment # 21 on bug 1220119 from Jiri Wiesner

Petr, I need to ask:
Is the log in comment 13 a composite, meaning collated from logs coming from
different boots of the VM?
As for the association between the test failure and the occurrences of the
clocksource watchdog error, does the clocksource watchdog error (or
"clocksource: Long readout interval...") always happen when the
ltp_net_tcp_cmds test fails?

It seems to me that, since causation has not been established, there could be a
hidden root cause causing both the test to fail as well as the (possibly
occasional) clocksource errors. Regarding kernel options, it is also possible
to use tsc=reliable, which is meant for virtualized environments, or
tsc=unstable to disable the watchdog checks.
