Hello,
I'm trying to switch to mISDN, but upon loading asterisk mISDN creates
an kernel oops. I'm using a custom configured vanilla kernel version
2.6.22.1 on gentoo. These are the versions I use:
[I--] [ ~] net-dialup/misdn-1.1.5 (0)
[I--] [ ~] net-dialup/misdnuser-1.1.5 (0)
[I--] [ ~] net-misc/asterisk-chan_misdn-0.3.0 (0)
[I--] [ ~] net-misc/asterisk-1.2.21.1-r1 (0)
I'm trying to use a hfc-pci card in NT-mode. The card get's properly
detected and configured by misdn. Here's the dmesg including the oops:

I haven't changed much in the configs. Upon load, asterisk simply
crashes... No clue where this oops comes from. Anyone?
Thanks
