		Hi there ppl,


	Pretty often 2 absolutely identical systems crash ( kernel
	panics )  with the messageL

	Fatal trap 12 while in kernel mode
	....
	....
	supersuser read, page not present
	process - PID (  different all the times)
	.....



	What exactly does it mean: 

	>> there is some bug in the kernel ( which I doubt, since kernel
	does intercept the exception) ?

	>> I've got shitty computers ( motherboard and/or memory) ?


	The systems are P120 Triton chipset, PCI SMC ethernet adapter,PCI 
	Adaptec 2940, PCI SVGA trident ( no X11).


	I've upgraded the systems to 2.1 stable ( both kernel
	and binaries ).


	Any suggestions ? Any particular PC's brand to use ( the systems
	are _very heavily loaded : ~3000-4000 accounts on ea.,~50-70
	users on-line).
