Hi,
I have made some changes to my kernel and I am trying to install the new
kernel.
I have configured the kernel using config -f.
While booting, the kernel panics with pagefault and repeatedly reboots. My
question is how do I get a crash dump of the kernel? How do I find the
problem?
Here the log message that came on the screen before rebooting:
Fatal Trap 12: Page fault while in kernel mode
fault virtual address = 0x20
fault code = supervisor write, page not present
Instruction Pointer = 0x8:0xf0194e2f
stack pointer = 0x10:0xf3357d4c
frame Pointer = 0x10:0xf3357dcc
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def 32 1, gram 1
processor ef flags = interrupt enabled, resume IOPL = 0
current process = 149 (sendmail)
Interrupt mask =
trap number = 12
Panic: page fault
What does the current process sendmail means? Is it the one under problem?
How do I get a dump of this kernel? How do I debug this?
Kernel version is: 3.1 FreeBSD
thanks in Advance
