I tested more intensively, by booting the system 5 times in a row:
--- try #1 -------------------------------------------------------------------
Mounting NFS file systems: .
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x103
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc023b308
stack pointer = 0x10:0xcb2a1e64
frame pointer = 0x10:0xcb2a1e68
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 111 (chflags)
interrupt mask = net bio cam
trap number = 12
panic: page fault
------------------------------------------------------------------------------
--- try #2 -------------------------------------------------------------------
Starting standard daemons: inetd cron printer sendmail
syncing disks... panic: softdep_deallocate_dependencies: dangling deps
------------------------------------------------------------------------------
Tries #3 and #4 were successfull.
--- try #5 -------------------------------------------------------------------
Doing initial network setup: hostname.
panic: vm_fault: fault on nofault entry, addr: c4f25000
------------------------------------------------------------------------------
As you can see, my system panics ~ 3 times out of 5 at boottime; I might
suspect a hard disk problem, previewing a huge disk crash.
What do you think?
Best regards,
