kernel panic when touch file in filesystem mounted with sshfs

[gallafent]

Hi All,

When I try to touch a file in a filesystem mounted using sshfs, the machine crashes hard, requiring four-second-button-press.

I cleaned and reinstalled sshfs and its dependencies. The install process went like this:

As you can see, all the dependencies were installed fresh.

However, the hard crash results. I will attach a sample session (in which I simply mount the remote fs with -d in case that's of any use), and the kernel crash log which is presented to me after the reboot! If instead of attempting to use it, I unmount the filesystem using umount, the sshfs process terminates and all is well!

Sounds like a bug that should be reported to the developers of sshfs.
