Hi all. Maybe you could help me figure out what's giving me these problems. On this particular computer I get these kind of errors a *lot*, almost always with the same instruction pointer. (This is running 2.1.5R, I had the same problems with 2.1R). Sometimes the machine will even "Freeze" and reboot in the middle of doing something with no warning..:] -- Fatal tral 12: page fault while in kernel mode Fault virtual address = 0xfc7 Fault code = supervisor read, page not present Instruction pointer = 0x8:0xf0181de2 Code segment = base 0x0, limit 0xfffff, type 0x1b DPL 0, pres 1, def32 1, gran 0 Processor eflags = interrupt enabled, resume, IOPL = 0 Current process = 249 (cpp) Interrupt mask = panic: page fault -- As I said it almost always happens on the same instruction pointer. The process can be anything but it usually occurs with gcc (such as when compiling the kernel, I can't even get a minute or two into the compile). Hardware: 16meg of parity ram, AMD DX4/100, SiS 85c471 chipset motherboard (ick!) with VLB bus, Adaptec 284x SCSI controller, S3 video card, etc. I will most likely be replacing the motherboard with a better one, but I would like to know if this is going to fix it? Thanks for any tips, pointers, ideas you can give me.. Forgive me if I type of message is not welcome in one or both of these mailing lists. - Steve - Systems Manager - Community Internet Access - http://www.cia-g.com
