Also using pccardd -i 3 did not work. There's a bug in the ata driver that Ian Downes has a patch for. Since cardbus bridges are now using level interrupts to allow sharing (which is why it used irq 9, the same as your bridge), cards that assert interrupt, but don't clear it, will cause the machine to hang in an interrupt storm. Ian's patches fix that. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
