I've attached the dmesg output. By the way, I'm a retired hardware/firmware/software designer from the olden days (1980s through early 2000s), specializing in embedded systems. So I've done everything from designing simple CPUs and microcontrollers, to firmware and simple RTOSs, to assemblers and high level software, including Linux. Heck I was working before things like Linux and GDB even existed! :) So if you need me to do something more complex I'd be happy to try. I'm pretty rusty though, so I don't know if trying to instruct me would help or hurt :) -- You are receiving this mail because: You are watching the assignee of the bug.
