Hi, I've got an issue with my HP Compaq nc6320, where it won't boot off its battery without softlocking on CPU#0. I remember it booting ok off battery occasionally in the past, but once I've seen the fault - the only way I can get it to boot is off AC. (I usually boot off AC anyway). I'm presuming ACPI as a good starting point, since that is an area where AC / Battery may make a difference. Can anyone suggest a debugging procedure to identify the cause of a softlock, and where would be appropriate (which category) to file a kernel bug for this? -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!) - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
