The machine runs mostly OK for several days. Only under heavy load it breaks down quite immadiatelly. It seems that there is a problem with swap. Some apps cannot be started and show the message "kvm_read kvm_read: bad address". One of these apps is "dmesg". This occures very irregularly, mostly quite after booting. Some minutes later (in case the machine is still running ;-)) also dmesg works fine again. The same environment works very steadily with the GENERIC 970124-SNAP kernel. Can it be a bug in the SMP kernel or is it because of the differences between the SNAP and the kernel version? Or do I have some misconfiguration in my kernel? The kernel config file is included at the end of this mail.
