Red Hat Bugzilla – Bug 170188
Machine hanging on (remote) reboot: psmouse.c: bad data from KBC - timeout
Last modified: 2012-06-20 09:19:45 EDT
When we upgraded one of our servers to redhat enterprise server 4 update 4 it
refused to come back online.
After sending someone to the datacenter, he found that the error printed on
screen: "psmouse.c: bad data from KBC - timeout", and stopped booting there
This is after it was booted to the 2.6.9-22.EL (smp) kernel
After the machine was brought back online, dmesg is still slowly filling up with
psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 1 bytes
psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 2 bytes
Now the machine has had problems before, during 'firstboot' initialization the
last command that it tried to run was a set keymap command, which zombied and
restarted a lot of times, we finished rhn-register etc remotely so we could keep
using the machine.
Oddly enough during install it all worked perfectly, it was after reboot that
this problem happened. It was initialy installed with RHEL 4 Update 1, wich had
Now the fact that it doesn't have a working mouse isn't such a huge deal, its a
quad xeon servermanaged thru ssh so it can live without one, but that it stops
it from successfully rebooting is a big deal, next time we have to upgrade +
reboot it, or have a power crisis, it will mean traveling to the datacenter again.
We have about 14 rh el licences/servers of the same kind of configuration, but
without this behaviour, so i expect its a faulty bit of hardware for the mouse?
(speculation) but still thats no reason to keep the server from rebooting :-)
