smc-ircc freeze kernel

Hello,

I use 2.4.19 kernel with notebook Dell Latitude CPx J650

I modprobe these modules:

irlan                  19252   0 (unused)
smc-ircc                6720   1
irport                  4856   0 [smc-ircc]
irda                   81744   1 [irlan smc-ircc irport]

kernel tells me:
found SMC SuperIO Chip (devid=0x09 rev=08 base=0x03f0): FDC37N958FR SMC IrDA Controller found
IrCC version 1.1, firport 0x290, sirport 0x3e8 dma=3, irq=0
IrDA: Registered device irda0

ifconfig tells me:
irda0 Link encap:IrLAP HWaddr 00:00:00:00
UP RUNNING NOARP MTU:2048 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:8
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Base address:0x3e8

then when I simply tells:
ifconfig irda0 192.168.1.1 netmask 255.255.255.0
my kernel freeze after 3 seconds and only numlock and scrolllock blinks

I dont have any other computer on other side at the moment I write ifconfig.

Thanks for solution

Michal

Works fine here on 2.4.20-pre5, gcc-3.2, Dell CPx750J with the
same IR chipset you have.
