Something in 2.6.24-rc* seems to be a lot more fussy about this kind of situation than in 2.6.23. I have a driver (sata_qstor) that manages a piece of hardware that unfortunately generates spurious interrupts regularly. With 2.6.23, it was only rarely bad enough to cause the "Disabling IRQ #nn" event to occur. But in 2.6.24-rc*, it happens almost immediately now (so, yes, I've gone and put a workaround into the driver for it). Something's different. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems?
