The .config you posted earlier stated that you had both UP_APIC and APM_DISPLAY_BLANK enabled. Your dmesg log indicates that you're running on a 1.6GHz Athlon-XP, but there's no mention of APIC anything in the dmesg log. So either your Athlon has had its local APIC disabled, or you changed the .config to exclude UP_APIC. In any case, APM_DISPLAY_BLANK is known to sometimes lock up when it blanks the console (e.g., when X exists). This is because some graphics card BIOSen can't handle local APIC interrupts (e.g., the timer). The workaround is to disable either APM_DISPLAY_BLANK or UP_APIC. /Mikael
