When I get netconsole working, I'll be posting the logs. Are CONFIG_HIGHRES_TIMERS and CONFIG_NO_HZ enabled ? Yes, they are both set to Y in .config A new thing I have seen is that reboot doesnt work.... issue the command reboot and it shuts down linux, blanks the screen, but doesnt actually reset the machine... it stays in that state until you power off (holding the PWR button) Below is some of the info you requested, but I do realise logs are needed, and am on that case right now.. (just needed to let the power button recoder from its morning of abuse) Richard -======================= TEST 1 ========================== 1) NO COMMAND PARAMETERS Booted OK, but hun after a few minutes..
