The IRQ should be determined by examining the machine's : actual resource configuration, with a manual override from the loader. : Of all the possible sources of IRQ configuration information, the kernel : configuration file is the most likely to be wrong. Why is pcic different than every other device in the entire system? If I want to change the IRQ for a sio line, I do it in userconfig, not some whacked out kernel loader env variable. Why should PCIC be different? Also, this rusian roulette of picking an IRQ is unwise. It breaks too many times. You must hardwire the IRQ, or use polling. Examining the machine is too unreliable to work. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
