I'd been running the stable (2.6.1-rc1) version for a while. I was having problems getting a couple usb devices working (Canon digital camera and Nomad jukebox). I'd heard on gentoo-user that upgrading to 2.6.2 had resolved this issue for someone else. When I tried to get 2.6.2 via gentoo-test-sources, it was masked. Setting ACCEPT_KEYWORDS didnt help, so thats when I upgraded gentoo-dev-sources.
My issue with the usb devices is resolved. Everything works great. However, on boot hotplug tried to load the ieee1394 module. Currently I dont have any firewire devices or anything that uses the port, so I've removed support from the kernel to work around the oops. But this used to work in 2.6.1-rc1. Or at least it didnt used to oops :)
Anyways, this is an FYI in case no one has mentioned it. The port in question is on a creative labs audigy. The stack trace is below. If this is something I should take upstream to lkml, let me know. I'm just not sure if its a vanilla kernel problem or a gentoo post patch issue.
Thanks for your consideration. If there are any other details I can provide, let me know. I've only been using gentoo for a couple months so I'm not sure of proceedure in many cases.
