(By the way: I compiled the probing for a NE2000 Ethernet-Card into the kernel, but at the moment, there is no one in my computer.) >Description: In the case i make some swap-intensive compiles, after a while the following error-message appears: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x218 fault code = supervisor read, page not present instruction pointer = 0x8 : 0xf010f175 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres1, def32 1, gran1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 4(update) interrupt mask = net tty bio panic: page fault I don't think that this is a hardware problem, because my System runs under OS/2 and Linux without any problems. (At the moment :-)) My last thought was, that it could be a problem with a too little Swap-Space, but the *swapinfo* program shows only a usage maximum of 57%. >How-To-Repeat: That's no problem for me to reproduce this error, every time I make some swap-intensive compiles, this error comes up. (To reproduce I try to compile *ddd* and *plan* at one time) >Fix: >Audit-Trail: >Unformatted:
