I have some interest problem in FreeBSD 5.2 - 5.3. Funny, but 5.1 is not implement for this problem. Problem description: when I try to switch PAE mode (I have 8 Gb installed memory), I have many problems with kernel. It's happening when making lot of proccesses (for forcing this problem I used ForkBomb-1.3 in ports collection).
When I typing: #forkbomb --runasroot -f (this will make lot of proccesses) kernel panic has appear
Fatal trap 12: page fault while in kernel mode fault virtual address = 0xbffff000 fault code = supervisor read, page not present instruction pointer = 0x8:0xc045e830 stack pointer = 0x10:0xf2dd89e4 frame pointer = 0x10:0xf2dd8a18 code segment = base 0x0, limit 0xfffff, type 0x16 = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 495 (forkbomb) trap number = 12 panic: page fault
Sometimes, this appear:
panic: pmap_enter: invalid page directory pdir=0x8f1063, va=0xffe00000,
sometimes this:
panic: could not copy LDT,
and this:
panic: vm_fault: fault on nofault entry, addr: e796a000
I found, that this problem is in the pmap_qremove function (I think so...)
Please, help!!!!!!
P.S. In message attachment, I give you copy of my GENERIC and dmesg.boot files
