It happens with all kernels I have on the machine (fedora kernels 2.6.9... through 2.6.11). Once it happens I can only reboot the computer using Alt-SysRq key. I happened to be in the terminal window during one of the lockups, and kernel gave out some info, but most of it scrolled off the screen (nothing went to /var/log/messages). Similarly, trying to get info with Alt-SysRq does not help because most of the info is off the screen. I do not have an easy way to redirect this output somewhere through the serial port. I would appreciate any help in either capturing the output of Alt-SysRq or more generally diagnosing the problem. I will recompile the kernel if needed for diagnostics. Please cc the answer to shirman@lanl.gov Thanks, Yuri Shirman -- Yuri Shirman
