>Description:
Some time around or after August 3, any device other than ata assigned IRQ 15
in a Compaq Proliant ML530 no longer works.
August 3: sym driver works with SCSI controller on IRQ 15
August 5: sym driver no longer attaches but ncr attaches instead to SCSI
controller on IRQ 15
August 18: (dmesg output above) Neither sym/ncr nor fxp works on a device
assigned IRQ 15. There is an instant panic just after the sym driver
attempts to attach to the SCSI controller while it is using IRQ 15 (doesn't
even probe the rest of the devices or make it to a root mount attempt).
Notice the presence of ata0, which is not supposed to exist on these
systems. Only ata1 is supposed to exist, if I recall correctly. I will do
some more investigative work by booting several earlier kernels and attempt
to narrow down the exact problem date. I've already done a minor amount by
booting two previous kernels from the above dates and noting the results.
>How-To-Repeat:
Boot a recent 4.1-STABLE kernel on a Compaq Proliant ML530 with a device other
than ata assigned IRQ15.
>Fix:
A temporary workaround is to lock all device resources down in the system
configuration utility and keep them away from IRQ15.
