Hi,
All of the other interrupts from 0x0-0xf are set as Edge triggered in
the mptable, so that seems likely.
Fine. Second reason might be that the ExtInt pin is wrong for the APIC. I mean
it is set wrongly. To which pin sets the original BIOS the ExtInt IRQ?
Can you dump here the 0x4d0 and 0x4d1 so we can check how the level/trigger
is set.
Again I'm ignorant. How do I dump those values?
You arent, its important to ask!
#isadump -f 0x4d0
you should see the two bytes decoding at 0x4d0 and 0x4d1.
bit0 at 0x4d0 is IRQ0, bit7 is IRQ7
0 is level
1 is edge
This is set by linux.
