All this is happening on a HP NC8000 Laptop. I tried to configure my PCMCIA WLAN Card (Allnet ALL0282A; AR5211 chip) recently. First thing I wanted to do is to scan for networks, so I set the card "up" and noticed a lot of Interrupt storm warnings on the console: interrupt storm detected on "irq10:"; throttling interrupt source The network scan didn't succeed btw. I tried another WLAN Card: Conceptronic C54RC (Version 2.0) R61 chip but the exact same thing happened again. I then tried a serial card (PCMCIA card that offers a COM-Port) and when booting up, I got those storms as well. I used the following command to determine, which driver handles IRQ10: "ps ax | grep irq". The following showed up: 22 ?? WL 0:00.57 [irq10: cbb0 cbb1+*] Therefore I suppose there is a bug in the interrupt handling in the cbb driver, because all these card work (on the same machine) under Linux and Windows XP. How-To-Repeat: Plug in some PCMCIA Card.
State Changed From-To: open->feedback Can you still reproduce this on recent FreeBSD versions?
That's a yes: I've just tried 9.0-BETA3 and the interrupt storm still occurs.
State Changed From-To: feedback->open Still a problem on 9.0-BETA3.
Hi all, I have the same problem on 9.0 RELEASE. Wireless card driver is ath. Interrupt storm dramatically slows my system. -- With best regards, Konstantin Vasilev
