Problem with kernel 2.6.5 and gm 2.1.1

Hi,

i just have installed the new SLES9 Beta 3.5 on a JS20 system. I have
configured and compiled the 2.6.5 kernel to have a correct linux source
tree and then build the gm 2.1.1 driver. I installed the gm package and can
start it with /etc/init.d/gm start.

Here is the output of the start command:
Apr 27 10:07:05 seoul kernel: gm: module license 'Myricom' taints kernel.
Apr 27 10:07:05 seoul kernel: GM: Version 2.1.1_Linux_rc20040402140653PST

And if i do a ifconfig myri0 i get this:
seoul:/tmp/BUILD_ROOT/binary # ifconfig myri0

          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

I can even see the board with gm_board_info and get the following output:
seoul:/tmp/BUILD_ROOT/binary # /opt/gm/bin/gm_board_info
GM build ID is "2.1.1_Linux_rc20040402140653PST

Board number 0:
  lanai_cpu_version = 0x0a00 (LANai10.0)
  lanai_sram_size   = 0x001fe000 (2040K bytes)
ROM settings:
  MAC=00:60:dd:49:46:1d
  SN=176475
  PC=M3S-PCIXD-2-I 73P6015
  PN=09-02707
LANai time is 0x01236e51c ticks, or about 2 minutes since reset.
Packet Interface 0:
  Mapper is 00:00:00:00:00:00.
  Map version is 0.
  0 hosts.
  Network is NOT fully configured.
This node is "seoul"
Board has room for 16 ports,  511 nodes/routes,  8192 cache entries
          Port token cnt: send=61, recv=254
Port: Status  PID
   0:   BUSY 12088  (this process [gm_board_info])
Route table for this node follows:
gmID MAC Address                                 gmName Route
---- ----------------- --------------------------------
---------------------
   1 00:60:dd:49:46:1d                            seoul [0] (this node)

But then the program just stops. I guess that it blocks somewhere in the
kernel, because if i do a "ps", it also seems to block in the kernel. So i
also cannot try to kill the process and CTRL-C doesn't work.

My guess would be some problem with the 2.6.5 kernel. Can anyone help?
