Hello,
thanks for your reply. Due to a lot of work "at work", I did not yet
manage to report the bug, but I will do so soon.
Today I want to add my current uptime and interrupt state for a last
time, as I might have to power down the system in a few days for
maintenance measures (and anyway want to put and end to ompelled uptime
watching related to this bug). In addition to the flawless uptime, the
complete system and all running tasks have proven to be absolutely
flawless over this amount of time (well, that's the way I expect it from
a Linux operating system as long as no very risky software is running -
but it also confirms that the hardware really has no problems and my
problems were only related to the "lockup detector". Even the amount of
shared interrupts and their dependencies on the APIC system and correct
driver implementations don't hurt. No kernel errors have been logged
since 17 July, and these were link down/up messages due to a switch
reboot...
