We can use the channel pin mask to check how many pins are currently being used to generate IRQs on this channel/vector. Here's what I've just tried. It solves my problem but I haven't tried enabling and disabling IRQs on all combinations of pins and vectors. diff --git a/targets/T...

or have a device not work when it tries to reassign the IRQs that are set up by the BIOS. You can prevent Windows from dynamically allocating ISA interrupts by turning off IRQ steering. This prevents Windows from dynamically allocating interrupts, and relies on your system BIOS to do so. ...

NMI Watchdog detected LOCKUP on CPU 14 and triggered the kernel panic. The cause of the NMI watchdog crashing the system is due to having IRQs disabled for too long. The timeout for a NMI watchdog to trigger is 30 seconds. The evidence in vmcore indicates that theemcpmodule has tried ...
PCI devices can share the same IRQs because the system BIOS builds a table that is called the PCI IRQ routing table. This table includes entries for each PCI device that is given an ISA IRQ that is mapped to a particular PCI INT number that is associated with the ...
