my sir of laptop don't run, why?

[eldruida <dru...@gm...>]

Hello, Sorry for my english.

I have a acer aspire 1356 with built-in port ir run in lfs system. It seems
to be a sir chip ( Windows tell is a nsc6001).

I have compiled lirc 0.8.1 with sir irda and then i have loaded the module
with no warnings, but when i run irrecord, it not detect any signal.

What is wrong.

The output of kernel when load modules is:

shell#: modprobe lirc_sir irq=3

lirc_dev: lirc_register_plugin: sample_rate: 0
IRQ handler type mismatch for IRQ 4
current handler: uhci_hcd:usb1
 [<c012d056>] setup_irq+0x18a/0x1a3
 [<e09fd6c2>] sir_interrupt+0x0/0x1c2 [lirc_sir]
 [<c012d0ec>] request_irq+0x7d/0x99
 [<e09fd1c2>] init_module+0x75/0x288 [lirc_sir]
 [<c012b340>] sys_init_module+0x13a7/0x14f2
 [<c0102a3c>] sysenter_past_esp+0x5d/0x81
 =======================
lirc_sir: IRQ 4 already in use.
lirc_dev: lirc_register_plugin: sample_rate: 0
lirc_sir: I/O port 0x03f8, IRQ 3.
lirc_sir: 0xff
lirc_sir: Installed.

What i can do?


Thanks
