Hi all,
I have come across a bug that triggers a kernel panic on 8.1-STABLE(r213395) through the
use of /usr/ports/sysutils/fusefs-sshfs. Typically i do an sshfs mount as such:
#sshfs username@hostname:/home/username local_mountpoint/
This mounts the remote filesystem fine. However, when i edit and save a file in
say vi on the remote sshfs i get the following panic everytime:
FreeBSD/amd64 (hostname.com) (ttyu0)
login:
Fatal trap 12: page fault while in kernel mode
cpuid = 2; apic id = 02
fault virtual address = 0x0
fault code = supervisor read instruction, page not present
instruction pointer = 0x20:0x0
stack pointer = 0x28:0xffffff80e9d1d9d0
frame pointer = 0x28:0xffffff80e9d1db50
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 1749 (vim)
trap number = 12
panic: page fault
cpuid = 2
Uptime: 17m11s
Physical memory: 8096 MB
Dumping 1591 MB:
It then seems to hang and not actually do a dump and i need to physically reset
the box.
If there is anything i can do to further assist in debugging please let me know.
