Summary:                    Crash after configuring TE420
Description: 
I have installed DAHDi drivers, in a Ubuntu 8.10 server, and I rebooted.
Ubuntu reboots just fine and modules are loaded. DAHDI drivers sees
correctly my card as TE420.
Then I ran: dahdi_genconf and it creates /etc/dahdi/system.conf:
# Autogenerated by /usr/sbin/dahdi_genconf on Fri May 22 16:46:45 2009
# If you edit this file and execute /usr/sbin/dahdi_genconf again,
# your manual changes will be LOST.
# Dahdi Configuration File
#
# This file is parsed by the Dahdi Configurator, dahdi_cfg
#
# Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER) 
span=1,1,0,ccs,hdb3,crc4
# termtype: te
bchan=1-15,17-31
dchan=16
echocanceller=mg2,1-15,17-31

# Span 2: TE4/0/2 "T4XXP (PCI) Card 0 Span 2" 
span=2,2,0,ccs,hdb3,crc4
# termtype: te
bchan=32-46,48-62
dchan=47
echocanceller=mg2,32-46,48-62

# Span 3: TE4/0/3 "T4XXP (PCI) Card 0 Span 3" 
span=3,3,0,ccs,hdb3,crc4
# termtype: te
bchan=63-77,79-93
dchan=78
echocanceller=mg2,63-77,79-93

# Span 4: TE4/0/4 "T4XXP (PCI) Card 0 Span 4" 
span=4,4,0,ccs,hdb3,crc4
# termtype: te
bchan=94-108,110-124
dchan=109
echocanceller=mg2,94-108,110-124

# Global data

loadzone	= us
defaultzone	= us

Which seems correct for my card.

When I ran dahdi_cfg then my computer freezes and I need to press the
power button long enough to power off.

After I restart the system, Ubuntu crashes with:
NMI received, reason 2d on CPU 0.

The system hangs, and I need to power off, remove the card from the slot,
and then Ubuntu starts OK.

Tried with acpi=off during boot, also disabled NMI errors in BIOS, but
still I get the same result.

What am I doing wrong here? Should I try another combination of drivers
and Asterisk? By the way, I have Asterisk 1.4.21.1 installed.
