I have a USB FM transmitter I used to have set up properly, but the computer it was on had to be reformatted. So tonight before I head to bed, I decide to hook it up to again.
Naturally, I figure since it was working before, it’d be a snap. Nope. After some dreary googling, I finally see a single offhand comment on a newsgroup, that doesn’t solve the problem being discussed. However, it solves mine and I get an explanation, too!
Times like these makes me wonder at how much I enjoy tinkering and solving problems. I’m doing this just so that I can have my digital music shuffled and playing when my radio alarm goes off, yet it extracts as much diligence and effort as my day job where I’m paid the money I use to eat and play.
It must be all the time with Lego as a kid. ^_^
What was the problem? Well, the box I was using is a little old, a Pentium III. Apparently, the motherboard isn’t handling interrupts issues for USB via APIC (whatever that is) properly, as seen by looking at “/proc/interrupts” (the device was listed, but the interrupt counter wasn’t budging from zero). Thanks to the newsgroup post, I learned to add “noapic” to the boot up kernel arguments, and voila!
