I have a Tyan Trinity GC-SL (S2707). After the recent (mid or late November) improvements to ioapic interrupt handling, irq 20 seems to be broadcast to ACPI. Ie: % vmstat -i interrupt total rate irq4: sio0 173 6 irq6: fdc0 4 0 irq8: rtc 3118 124 irq13: npx0 1 0 stray irq13 1 0 irq14: ata0 1154 46 irq15: ata1 30 1 irq31: fxp0 261 10 irq0: clk 2436 97 Total 7178 287 # load driver which uses irq20 % sudo kldload gm.ko # generate some interrupts on irq20 % gm_allsize -g --blocking-no-spin >& /dev/null % vmstat -i interrupt total rate irq4: sio0 1531 22 irq6: fdc0 4 0 irq8: rtc 8780 127 irq9: acpi0 6430 93 irq13: npx0 1 0 stray irq13 1 0 irq14: ata0 1300 18 irq15: ata1 30 0 irq20: gm1 6430 93 irq24: gm2 1 0 irq31: fxp0 678 9 irq0: clk 6858 99 Total 32044 464 Note how irq20 has the same number of interrupts as the acpi device at irq9. I've tried http://www.freebsd.org/~jhb/patches/acpi_irq.patch, but it didn't help. I've left verbose dmesg, mptable, and acpi info at http://people.freebsd.org/~gallatin/trinity. This boot was with the acpi_irq patch appied. FWIW, this motherboard has always caused acpi to squeal like stuck pig... Drew
