I have been experiencing hangs on a newly setup machine. Unfortunately, it appears to be hanging inside the interrupt handler as sysrq and caps-lock led seem to stop working when the event occurs. I am guessing it is related to the sata_promise driver, but that is only a guess as I don't get much for output. I am running the debian unstable kernel (2.6.22-1-686), but the problem also occurs with the debian stable kernel (2.6.18-4-686). I do need to boot with the acpi=off option, but am not sure if that is related. Unfortunately, I do not know much about troubleshooting i386 when problems occur inside the interrupt handlers.
What can I do to help troubleshoot this problem. Thanks, Robin Holt PS: A little background information: # lspci -v ... 00:0b.0 Mass storage controller: Promise Technology, Inc.
