Set kernel logging to be sent to a serial port and attach another device
(terminal, PC etc) to record what it sees there.

Thanks Dave!

It appears that the problem was with it booting with acpi=off. 
Curiously, of the five new servers that we just bought, four of them 
suffered from this problem and the other one didn't.


Onwards to the next problem...

[opensuse] midnight crashes (10.3 on IBM x3455)

2007-11-22 Thread Anna Langley 

Dear All,

I am trying to get to the bottom of a problem with running 10.3 on IBM 
x3455 servers (2x dual core opteron).


The machines crash without fail, exactly on midnight if the hardware and 
system clocks are synchronised.  They also crash less predictably when 
the hardware clock reaches midnight.


The crashes are so swift and complete that nothing gets written to the 
system, BIOS or BMC logs.


If any of you have seen a similar fault, I'd like to hear from you and 
compare notes. And I'll summarise the outcome here for everybody's benefit.


Cheers,

Anna
