  Interrupt - Wikipedia, the free encyclopedia
Software interrupts are usually implemented as instructions in the instruction set, which cause a context switch to the interrupt handler similarly to a hardware interrupt.
Interrupts may be implemented in hardware as a distinct system with control lines, or they may be integrated into the memory subsystem.
In some cases, such as the x86 architecture, disabling and enabling interrupts on the processor itself acts as a memory barrier, in which case it may actually be slower.

 Storm - a short story
Storm was not as happy as the other children of the giants, while they were playing he sat aside on a cloud and thought.

 cvs commit: src/sys/dev/uart uart_dev_ns8250.c   (Site not responding. Last check: 2007-10-11)
If the interrupt is level-senstive and floats high, then it should be active-low so that there is not an interrupt storm from the spurious interrupt (and not even a single spurious interrupt) for the level-sensitive case.
In the SMP case, other CPUs may see the interrupt, but if it is shared with an sio device then they will block and not see a storm; if it is shared with a non-sio device, then they may see a storm.
In both cases, the CPU running the probe is unaffected and eventually handles the interrupt, so the interrupt or storm seen by the other CPUs goes away.

 Error Message: An Interrupt Storm Has Caused the System to Hang
A device driver ignores the interrupt signal that had been initiated from its hardware and the device driver does not instruct its hardware to release the interrupt signal.
An interrupt storm is defined as a level-triggered interrupt signal that remains in the asserted state.
Parameter 1: The address of the ISR (or the first ISR in the chain) that is connected to the storming interrupt vector.

In a situation such as an approaching tornadic storm, unless you have priority or emergency traffic, please stand by with your traffic until the emergency weather situation is resolved.
Storms can move as fast as 90 miles per hour, and can be quite fickle in their movements...changing direction before you realize it.
Watching a severe storm rapidly approach you is NOT the time to discover that your battery just bought the farm, or realize that you have a flat tire, etc. Be sure you're able to get fuel, etc. for your vehicle especially after dark...many small towns, as noted above, close many of their businesses at dusk.

 Problems updating FreeBSD's card system from ISA to PCI   (Site not responding. Last check: 2007-10-11)
The solution adopted by the author was to route the function interrupts to the ISA bus until the driver had attached an interrupt status routine.
If one is routing interrupts for a given device, and another device has routed an interrupt on the wire that, there is no choice in which interrupt gets routed.
After porting most of the PCI interrupt code to 4.x, I was able to use many of the machines that had previously had unassigned interrupts for the PC Card bridge.

 PCMCIA IRQ Routing on Windows XP
If a device appears that requires an ISA interrupt (which is relatively common for 16-bit PC Cards), the device cannot function and may cause system-wide problems, such as interrupt storms.
The Interrupt Service Routine (ISR) in the driver for the card was not designed to return the proper indication that a given IRQ was generated by its respective device.
However, if a device that does not support PCI interrupts is inserted into a CardBus slot in this system, it will not function and may cause system-wide problems, such as an interrupt storm.

 CATHOLIC ENCYCLOPEDIA: Martin Luther
During his absence at the Wartburg (3 Apr., 1521-6 March, 1522) the storm centre of the reform agitation veered to Wittenberg, where Carlstadt took up the reins of leadership, aided and abetted by Melancthon and the Augustinian Friars.
In the narrative of conventional Reformation history, Carlstadt is made the scapegoat for all the wild excesses that swept over Wittenberg at this time; even in more critical history he is painted as a marplot, whose officious meddling almost wrecked the work of the Reformation.
True, when too late to lay the storm he issued his "Exhortation to Peace", but it stands in inexplicable and ineffaceable contradiction to his second, unexampled blast "Against the murderous and robbing rabble of Peasants".

That is, those interrupts are not coming from the card.
Since resetting the 8390 stops it from madness, its likely that the card itself is sending the interrupts, no? Interesting...
