System runs latest FC5 x86-64 kernel (2.6.17-1.2139_FC5) System might suddenly hang hard or reboot.
Seems to blurt sporadic errors to syslog.

The system has rebootet twicein 3 days, this time it did not reboot but some processes have hung. Running ps ax was a bad idea, as that hung too.
crash utility just fails with the following error: crash: cannot resolve "cpu_pda"
For more info just ask. I might reboot it but I'm sure it's not going to be far between crashes.

Does the box have ECC memory ?
No, but it does not fail memtest86+ (the version that is on the FC5 cd) It is unstable on both of these atleast: kernel-2.6.16-1.2133_FC5 kernel-2.6.17-1.2139_FC5
We are also having trouble with an IBM 4x P3-xeon 700Mhz box using the same two kernels. It's located 10 hours from here so I'm not very likely to get access to oops messages. (their technician is on vacation so I have to coach the whoever-is-available staff when something goes wrong). But this does come up on boot:

Not sure whether it's related or not.

Are both the serial port and one of the other devices assigned the same legacy IRQ (3 or 4) ?

I have a ThinkPad T42p (Pentium M cpu).
With kernel-2.6.17-1.2139_FC5 I can get about 5 mins of uptime (about enough time to open my email and browser) before it freezes solid.
I'm going to setup netconsole (no serial port on this laptop) and see if I can capture anything useful.
Looks like others are having trouble too:

Now on 2.6.17-1.2145_FC5 still shows problems, this time it complains about page_mapcount beeing -1. And after that there is a Kernel BUG message curiously mentioning /block/hdd/removable aswell. But this time it seems it's mysqld that crashed?
I'm confused as to what is causing this since memtest86+ does not find anything wrong. There are also no new bioses available.
