Hi, I just got another machine failure. This is happening every 10 minutes - it is rubbish. A sample of the format of message set that is generated is listed below. This set did not "flash" past on the console in a scrolling blizzard - the machine has just "frozen" Message format on the "console" [<nnnnnn>] -call console_Drivers +0x ... etc [<nnnnnn>] -do page_fault +0x ... etc [<nnnnnn>] -show trace [<nnnnnn>] -show_stack [<nnnnnn>] -show_registers [<nnnnnn>] -die +0x ... etc ..... Again. Are these message swritten to a log file so I can post a sample? Thanks Clive
