Hi. I'm running 2.2-GAMMA, on a DTK motherboard w/512kb, with a Cyrix P150+ processor and 48MB RAM. There are 3xIDE 1 gig drives, a SMC EtherPower NIC and a Diamond Stealth 64. Over the last four days, my machine keeps breaking into the debugger, with the following : Fatal Trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0x0 stack pointer = 0x10:0xefbffe54 frame pointer = 0x10:0xefbffe5c code segment = base 0x0, limit 0xfffff, type 0x1b = dpl 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 248 (halt) interrupt mask = kernel:type 12 trap, code=0 (Sorry for any typo's - difficult to type this stuff) I haven't changed anything recently, except for world'ing 2 days prior to these traps. I suspect it's hardware based, because I've put the drives into another machine and it works fine (although MUCH slower - 486's still work :-) Any pointers on how to see what the exact problem is ? Does the above trap help ? I've tried various combinations of RAM, wiggling everything in, etc, but it doesn't help. TIA, --- Khetan Gajjar [ http://www.iafrica.com/~khetan] I'm a FreeBSD User!
