Kernel panics

Show all headers | View raw

NOTE:  I am unable to convince Xnews to set the FollowUp-To to 
alt.os.linux.slackware. Please reply there.

Problem:
My internet-facing computer is experiencing kernel panics on an 
increasingly frequent basis.

Scenario:
The box was set up in July 2001.  AMD Duron CPU, 4 IDE drives in a 
software RAID-5 array, 2 NICs (LAN and WAN) and a Diamond Stealth 
video card.  When the kernel panics began to become more frequent, I 
added append = "panic=10" to lilo.conf.

General Info:
My understanding of "In interrupt handler - not syncing" is that some 
hardware is at fault, but that seems not to be the case here.  I have 
2 other boxes with Intel P4 CPU, IDE interfaces, PS2 kbd & mouse, a 
serial and a parallel port.  I changed the CPU in .config from 
CONFIG_MK7 to CONFIG_MPENTIUM4 (for the switch from AMD to Intel) and 
built bzImage and modules.  Then I removed the drives from the AMD 
computer and put them into one of the 2 Intel boxes.  Kernel panics 
were just as frequent.  On the off chance that that Intel box was also 
bad, I moved the RAID array to the other Intel box and kernel panics 
still continue.

Each of the 2 Intel boxes contains one of the NICs that were in the 
AMD box: the SMC uses the tulip driver and the 3com uses the 3c59x 
(3com "vortex") driver.  That NIC is connected to the cable modem.  
There is no other commonality other than the connections: power cord, 
keyboard, mouse, parallel printer, and serial port (battery backup but 
not monitored).

There is nothing in the logs to indicate any problem.

Request for a suggested course of action:
Should I replace one drive at a time in the array?  If so, why?
Should I reinstall the packages?  If so, why?
if this were your computer, how would you approach a solution?

Comments are also welome.  Please help if you can.
