Kernel Panics due to SMBFS (1.7) on 10.7 Lion

Hi Everyone,

I recently did a clean install of OS X 10.7 Lion, and am now having a regularly occuring problem with kernel panics due to smbfs (1.7). After mounting a Windows shared drive using samba, and then accessing files from this drive, a kernel panic occurs. It also seems to occur when attempting to dismount a samba drive. I did not have this issue with Snow Leopard at all, so I'm assuming it is an issue with Lion. I have copied the kernel panic below. Any ideas? Thanks everyone!
