Thanks for investigating this, but I propose another fix, namely to
remove soundmodem altogether. Linus, please do:
rm -rf drivers/net/hamradio/soundmodem
and then apply the attached patch.
Why?
* There is a usermode only replacement now (and for several years
already), which works with most OSS interface sound drivers
* The kernel stuff is limited to a few ISA cards, and nowadays
mainboards with ISA slots almost ceased to exist, same with ISA
soundcards
Thanks
Tom

-CONFIG_SOUNDMODEM
- This experimental driver allows a standard Sound Blaster or
- WindowsSoundSystem compatible sound card to be used as a packet
- radio modem (NOT as a telephone modem!), to send digital traffic
- over amateur radio.
-
- To configure the driver, use the sethdlc, smdiag and smmixer
- utilities available in the standard ax25 utilities package. For
- information on how to key the transmitter, see
- <http://www.ife.ee.ethz.ch/~sailer/pcf/ptt_circ/ptt.html> and

- If you want to compile this driver as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/modules.txt>. This is
- recommended. The module will be called soundmodem.o.
-
-CONFIG_SOUNDMODEM_SBC
- This option enables the soundmodem driver to use Sound Blaster and
- compatible cards. If you have a dual mode card (i.e. a WSS cards
- with a Sound Blaster emulation) you should say N here and Y to
- "Sound card modem support for WSS and Crystal cards", below, because
- this usually results in better performance. This option also
- supports SB16/32/64 in full-duplex mode.
-
-CONFIG_SOUNDMODEM_WSS
- This option enables the soundmodem driver to use WindowsSoundSystem
- compatible cards. These cards feature a codec chip from either
- Analog Devices (such as AD1848, AD1845, AD1812) or Crystal
- Semiconductors (such as CS4248, CS423x). This option also supports
- the WSS full-duplex operation which currently works with Crystal
- CS423x chips. If you don't need full-duplex operation, do not enable
- it to save performance.
-
-CONFIG_SOUNDMODEM_AFSK1200
- This option enables the soundmodem driver 1200 baud AFSK modem,
- compatible to popular modems using TCM3105 or AM7911. The
- demodulator requires about 12% of the CPU power of a Pentium 75 CPU
- per channel.
-
-CONFIG_SOUNDMODEM_AFSK2400_7
- This option enables the soundmodem driver 2400 baud AFSK modem,
- compatible to TCM3105 modems (over-)clocked with a 7.3728MHz
- crystal. Note that the availability of this driver does _not_ imply
- that I recommend building such links. It is only here since users
- especially in eastern Europe have asked me to do so. In fact this
- modulation scheme has many disadvantages, mainly its incompatibility
- with many transceiver designs and the fact that the TCM3105 (if
- used) is operated widely outside its specifications.

- This option enables the soundmodem driver 4800 baud 8PSK modem.
- This modem is experimental, and not compatible to anything
- else I know of.
-
-CONFIG_SOUNDMODEM_HAPN4800
- This option enables the soundmodem driver 4800 baud HAPN-1
- compatible modem. This modulation seems to be widely used 'down
- under' and in the Netherlands. Here, nobody uses it, so I could not
- test if it works. It is compatible to itself, however :-)
-
-CONFIG_SOUNDMODEM_FSK9600
- This option enables the soundmodem driver 9600 baud FSK modem,
- compatible to the G3RUH standard. The demodulator requires about 4%
- of the CPU power of a Pentium 75 CPU per channel. You can say Y to
- both 1200 baud AFSK and 9600 baud FSK if you want (but obviously you
- can only use one protocol at a time, depending on what the other end
- can understand).
