Hmm, that an intersting line of thought. The symptoms sound similar, that interrupts aren't necessarily been missed, since I can type when things seem locked up then it all appears. I get boatloads of these, they stream past continuously. ACPI-0448: *** Error: AcpiEvGpeDispatch: No handler or method for GPE[0], disabling event I have no idea what they mean though :-) I wonder if that might have something to do with it, or if it's triggering a problem somewhere in the dmesg buffer that's causing locks to be held too long. -- Paul Richards <paul_at_freebsd-services.com>Received on Sun May 11 2003 - 11:20:34 UTC
