Something really weird happening. I've returned sio.c to defaults, but my kernel still panics. I am no debugger, so I can't say where this panic occured. I have a dump, but don't know what do do with it. Seems like my system got damaged somehow (maybe by kernel crash while building kernel). So, I need a doctor :) -- Best regards, Oleg Tarasov mailto:subscriber@osk.com.ua
