Fresh install of 2.8.0.3 with a Rhino 4 port card. Every time I receive a call on channel 4, I get a kernel panic. Channels 1-3 are OK. Any ideas?

**more info: The Asterisk CLI prints the single line: '-- Starting simple switch on 'DAHDI/4-1'. The last couple of lines on the Linix console before lockdown are:
EIP: [] rcbfx_echocan_create+0x7f/0xb5 SS:ESP 0068:ce0caaf4
Kernel Panic - not syncing: Fatal exception

I'm supposed to go live on Monday and thought I was on track...until this.

fixed....sorta/maybe?? I set

I set 'echocancel=no' in chan_dahdi.conf and the panics stopped.
My card is a Rhino R4FXO-EC with hardware echo cancellation. Does anybody know if this setting disabled the redundant software echo cancellation, the hardware echo cancellation or both?
