This is a shared IRQ for > ath0 and echi0. Never saw this on 6.3??? Any suggestions? Just another contribution to the collection of interrupt storms maybe related to ath: Whenever I plug in my ath1 on cardbus0, I get exactly one storm: interrupt storm detected on "irq10:"; throttling interrupt source ath1: mem 0xd0220000-0xd022ffff irq 10 at device 0.0 on cardbus0 Anyhow, I am not sure, if it is really ath causing this. During boot, I get one storm, too, that is on irq 10, but my ath0 on pci2 is on irq 9: ath0: mem 0xd0200000-0xd020ffff irq 9 at device 4.0 on pci2 [...] interrupt storm detected on "irq10:"; throttling interrupt source I do not get interrupt storms on irq 9 and I have already had that storm before I replaced my minipci iwi0 with ath0: http://lists.freebsd.org/pipermail/freebsd-current/2007-October/078684.html The reply to that posting was that it is probably related to USB: http://lists.freebsd.org/pipermail/freebsd-current/2007-October/078687.html Moreover, I have a bunch of other devices sharing irq 10: vgapci0: port 0x3000-0x30ff mem 0xd8000000-0xdfffffff,0xd0100000-0xd010ffff irq 10 at device 0.0 on pci1 uhci0: port 0x1800-0x181f irq 10 at device 29.0 on pci0 uhci2: port 0x1840-0x185f irq 10 at device 29.2 on pci0 ehci0: mem 0xd0000000-0xd00003ff irq 10 at device 29.7 on pci0 fwohci0: mem 0xd0218000-0xd02187ff,0xd0210000-0xd0213fff irq 10 at device 7.0 on pci2 pcm0: port 0x1c00-0x1cff,0x18c0-0x18ff mem 0xd0000c00-0xd0000dff,0xd0000800-0xd00008ff irq 10 at device 31.5 on pci0 On our problematic irq, we both have got echi0. Thus, the second storm I get upon attaching ath1 might not be directly caused by ath. No suggestions, just more data. Cheers Jan Henrik
