I'm running: FreeBSD 5.3-STABLE FreeBSD 5.3-STABLE #0: Mon Jan 31 00:54:51 CET 2005 i386 The card is (Netgear WG311T): ath0: <Atheros 5212> mem 0xe7000000-0xe700ffff irq 9 at device 15.0 on pci0 After about 73 minutes uptime my PC is busy processing interrupts. Top shows 90% in IRQ. Everything is slowed down. Earlier kernels showed same effect. When the problem appears, I start "ifconfig ath0 down" then "ifconfig ath0 up" and everything is ok again for a certain period of time. Further info: IRQ 9 is being shared with ACPI (I tried to turn off ACPI, no effect). Earlier it was shared with my VGA-card, but showed exactly the same symptoms. The high interrupt load is not being reported like e.g. an interrupt storm on lpt. The system is simply slowed down. Martin
