In writing my device driver, I connect and disconnect my device quite a bit. Every so often I get this message. I typically reboot after I see it. I can't imaging anything described as "very bad" being something I should just blindly continue on with.
The machine is a Sony Vaio PCG-F650. I've got UCHI Alternate Driver (JE) compiled into the kernel. This is on kernel 2.4.20-pre4 pulled from the usb-2.4 bk tree. Here's the kern.log, let me know if there's more information you need.
