Hello.
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 = 0xb000
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc045e830
stack pointer = 0x10:0xf2dd89e4
frame pointer = 0x10:0xf2dd8a18
code segment= base 0x0, limit 0xf, 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=0xffe0,
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
