Summary: vmhgfs kernel module panics on FreeBSD
Initial Comment:
The problem reported in bug 3584833 suggests, the module has not been tested on
FreeBSD in a while... Indeed, after fixing the build, and trying to use the
module I get the following kernel panic (this is FreeBSD/x86 8.3, 32-bit):
Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 01
fault virtual address = 0x4

Examining frame #7 reveals:
(kgdb) p *l1
$1 = {prev = 0x0, next = 0xc7560000}
(kgdb) p *l2
$2 = {prev = 0x0, next = 0x0}
And then:
(kgdb) up
#8 0xc83adcdb in DblLnkLst_LinkLast (head=0xc6ff3644, l=0xc7560000)
at dbllnklst.h:286
286 in dbllnklst.h
(kgdb) p *head
$3 = {prev = 0x0, next = 0xc7560000}
(kgdb) p *l
$4 = {prev = 0x0, next = 0x0}
(It is possible, the problem reported in bug 3580633 is related.)
I have the core-dump with debug symbols, so, if anybody cares for more
variables, etc. let me know.
