Subject: PROBLEM: Oops when using emi62 with 2.6.28
When I plug my Emagic emi 2|6 soundcard into my system usually the emi62
module loads the firmware on the card and I can use it as a normal
usb-audio device.
With kernel 2.6.28 (and I don't really know which version of the kernel
introcudes this since I didn't use the card for quite a while) the
firmware gets loaded (the green lights on the card turn on) but the emi62
module crashes with an oops and then I can't use any usb device anymore
until I reboot.
Keywords: emi62 soundcard usb firmware oops
Kernel information:
Version: Linux pornomat 2.6.28 #2 SMP Wed Dec 31 15:11:53 CET 2008 i686 Intel(R) Core(TM) Duo CPU L2400 @ 1.66GHz GenuineIntel GNU/Linux
.config: see attachment
I don't know which version of the kernel does not have the bug but I
believe it worked with 2.6.27.2.
Oops:
