>Description:

my machine encounters a integer divide in kernel mode and finally reboots:

---
Fatal trap 18: integer divide fault while in kernel mode
mp_lock = 01000002; cpuid = 1; lapic.id = 01000000
instruction pointer  = 0x8:0xc0192c3b
stack pointer        = 0x10:0xc6e97c68
frame pointer        = 0x10:0xc6e97da0
code segment         = base 0x0, pres 1, def 321, gran 1
processor flags      = interrupt enabled, resume, IOPL = 0
current process      = 327 (mount_ntfs)
interrup mask        = SMP:XXX
trap number          = 18
panic: integer divide fault

>How-To-Repeat:

try 'mount_ntfs /dev/whatever /anydir' with 'whatever' being a type 7 partition, which must not
contain a valid NTFS.

such as 4.3-RELEASE?

 It was generally fixed on 1999/04/20 rev 1.3 of ntfs_vfsops.c - check 
 for `NTFS' signature in boot block. Think this could be closed.
