I want to connect a Linux PC (Redhat 4.2) with a SMC ATM Power 155 (eni
compatible) to our Digital GigaSwitch.

I use Linux 2.0.29 and atm-0.31, as I need Lane to connect to our LAN.

The Patch applies cleanly and everything compiles out of the box.

Only it seems that I dont get signaling to run.

On inserting the Module I get:
eni(itf 0): rev.0,base=0xfe800000,irq=10,mem=2048kB (00-00-C0-46-60-E0)
eni(itf 0): ASIC,MMF

When I start atmsigd I get (from dmesg):
atm_connect (TX: cl 1,bw 0-0,sdu 500; RX: cl 1,bw 0-0,sdu 500,AAL 5)

And in /var/log/atmsigd:
atmsigd:SIGD: Linux ATM signaling UNI 3.1/AAL5, version 0.31
atmsigd:SIGD: Acting as USER side
atmsigd:SSCF: entering state 2/2
atmsigd:IO: TO NET: ??? (0x00) CR 0x000101 (8 bytes)
atmsigd:IO: ----------
atmsigd:SSCF: entering state 4/10
....

Then I start ilmid -d -l /var/log/ilmid (dmesgoutput):
atm_connect (TX: cl 1,bw 0-0,sdu 484; RX: cl 1,bw 0-0,sdu 484,AAL 5)

/var/log/ilmid:
ilmid:ILMI: Linux ATM ILMI, version 0.31
ilmid:ILMI: sending cold-start
ilmid:ILMI: sending get-next
ilmid:ILMI: switch did not respond to get-next -- resending
ilmid:ILMI: sending get-next

ilmid:ILMI: switch did not respond to get-next -- resending

...

^^^^ And I believe that this will cause Lane, etc not to work

....

Then get(dmesg):
eni(itf 0): TX DMA full

I installed NT and Lane yesterday to verify that the Gigaswitch, cable setup,
hardware, etc. Works correctly and it worked, but I really want to use Linux.

P.S.:
This is what /proc says:
cat /proc/atm/devices gives:
Itf Type    ESI/"MAC"addr AAL(TX,err,RX,err,drop) ...
  0 eni     0000c04660e0  0 ( 0 0 0 0 0 )  5 ( 96 0 94 25 0 )

cat /proc/atm/pvc:
Itf VPI VCI   AAL RX(PCR,Class) TX(PCR,Class)
  0   0     5 5         0 UBR    353207 UBR   
  0   0    16 5         0 UBR         0 UBR   

cat /proc/atm/svc:
Itf VPI VCI   State      Remote
999   0     0 Signaling  

P.P.S.:
Is there any method to kill atmsigd, ilmid, aping, etc cleanly ?
I allways have to reboot to get rid of the prozesses as 
I can't kill them(ps auxww):
USER       PID %CPU %MEM  SIZE   RSS TTY STAT START   TIME COMMAND
