I don't know; I didn't follow the changes to the core signal-handling for kernel threads. I never experienced any problems until I started using 2.6.22, so it's certainly possible that you're seeing something different. I just tried doing what you said: modprobe net2280 dd if=/dev/zero of=/tmp/b bs=1M count=5 ; \ modprobe g_file_storage file=/tmp/b No problem; it worked fine. But my version of the driver includes the patch, of course. And this was under 2.6.22-rc3.
