>Description:
There is a problem with fusefs-kmod and FreeBSD 9.1 and rsync. While starting
rsync on fuse share, one encounters kernel panic with:
fuse4bsd: version 0.3.9-pre1, FUSE ABI 7.19
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x0
fault code = supervisor read instruction, page not
present
instruction pointer = 0x20:0x0
stack pointer = 0x28:0xffffff811b71bac0
frame pointer = 0x28:0xffffff811b71bb10
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 = 16502 (rsync)
trap number = 12
panic: page fault
cpuid = 0
