This is another oddity, I'm observing after an upgrade from 5.4-BETA to 6.0-BETA5 last night.
There are not IDE devices in the machine at all and the IDE controllers are
disabled in the BIOS (or so the BIOS says).
However, at boot time I get:
Interrupt storm detected on "irq14: ata0"; throttling interrupt source
and then the interrupts never cease, according to the 'systat -vm'
[...]

This knocks out one of my two processors of course... Nothing like this ever
happened in the 5.4 times...
The machine is an older Dell workstation with 2 PentiumII Xeons in it.
The ACPI never worked right on it -- whenever I tried enabling ACPI in the
BIOS, the machine would hang on boot. This is still happening now with 6.0 --
the hang is right after reporting the amounts of real and available memory.
