Hmm, that probably because I disabled the code that tries to deal with lost interrupts (its no good and can easily panic your box, thats why). We seem to be suffering from lost interrupts in -current for some time. I can on at least one system here confirm that the interrupt does get delivered from the device, but the ATA interrupt handler is newer called. Where the interrupt gets lost and why is still beyond me, anyone that can share some light on this is most welcome... -SørenReceived on Mon Oct 13 2003 - 00:28:30 UTC
