Been getting this quite a lot recently, with 10.6.4 clients and users with home folders mounted from smb shares on a 2008 Server.
Basically, when users occasionally log off (no real pattern found yet) then the Mac can ‘black-screen’ prompting the user to have to manually power the mac off and on again. Looking at the panic log, the issue is being caused by com.apple.filesystems.smbfs. The smbfs.kext file is v1.6.2, but I have read of similar issues on the web going back as far as v1.4 in Tiger.
My opinion is basically that the Mac is failing to let go of the mounted SMB shares of which there are a few, the home folder plus 3 other mounted shares.
I was going to get around this by installing File Services for Macintosh, however it appears this has been depreciated and removed from Server 2008. Nice one Microsoft.
Any assistance with this if this has been seen before would be greatly appreciated.
