Thanks for your kernel panic log. This doesn't prove anything, but 14 seconds before the oops involving ext4_delete_inode, there was a recursive fault in the X server, which was apparently running the Nvidia proproietary driver.
So I hate to ask this but (a) how many other people who have been having this problem are running with the proprietary Nvidia driver? And (b) would it be possible for people who can easily reproduce this, if they are using the Nvidia proprietary driver, to see if the problem goes away if you shut down the X server and logging into the VT console, and running the rm -rf from either a VT Console or via an ssh login?
It's *possible* that the Nvidia driver is innocent victim, and not the cause, but I don't use the proprietary closed-source Nvida driver, and I'm having a devil of a time reproducing the problem. So if we can take the closed-source Nvidia driver out of the equation, it would be useful to see where that leaves us.
Rocko,
