Rocky,

Try re-moving all non-essential external devices,
reboot and rerun the:
$ sudo wvdialconf  /etc/wvdial.conf
If there is not a Freeze, you can try adding devices back one-at-a-time
to  assess what causes the Freeze.

If  removing devices doesn't suffice, try shutting off services to
classes of devices with:
$ sudo gedit /etc/discover.conf

Change the lines:
-------------
# Default settings:
#
# Enable the PCI, USB, IDE, and SCSI bus scans:
enable pci,usb,ide,scsi
# Enable the PCMCIA scan too:
enable pcmcia
# The ISA bus scan causes problems on some machines, and is slow,
# so we might not want to scan these devices:
enable isa
#disable isa
# The parallel and serial scans cause problems on some machines too:
disable parallel,serial

# Scan for the following types of hardware at boot time:
#boot bridge,cdrom,disk,ethernet,ide,scsi,sound,usb,video
boot all
---------

TO

# Default settings:
#
# Enable the PCI, USB, IDE, and SCSI bus scans:
enable pci,ide
# Enable the PCMCIA scan too:
# enable pcmcia
# The ISA bus scan causes problems on some machines, and is slow,
# so we might not want to scan these devices:

#disable isa
# The parallel and serial scans cause problems on some machines too:
disable parallel,serial

# Scan for the following types of hardware at boot time:
#boot bridge,disk,ide
# skipping cdrom, ethernet,scsi,sound,usb,video
# boot all

Reboot and again test the modem.
If all is OK, the services can be added back one-at-a-time.

Much narrow choises can be later by adding driver names to a file with:
$ sudo /etc/modprobe.d/blacklist.local
# with lines like
blacklist ehci_hcd
# which only disable some USB ports

Merely blacklisted drivers can be manually after bootup with commands like
$ sudo modprobe ehci_hcd
