I have seen that 2.6.30 is out. I'm now running with 2.6.30 and tried to crash the ftdi_sio driver, I had no luck till now. So it seems to be fixed at least in 2.6.30, and I believe it was this patch: commit 80193195f87ebca6d7417516d6edeb3969631c15 Author: David Woodhouse <dwmw2@xxxxxxxxxxxxx> Date: Mon May 18 13:07:35 2009 +0100 Fix oops on close of hot-unplugged FTDI serial converter Best regards, Martin
