Hello,

There is a problem with fusefs-kmod and FreeBSD 9.2 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

current process                               = 16502 (rsync)

Same result can be obtained on FreeBSD 9.1

 

 

Any patches, advices ?

 

Thank you,

Luke
