Will provide irdadump stuff soon[-ish], I'm wading through a backlog
  of, uhm, too much email. The short-form report really meant "is this
  a known issue ?"...

Anyway - the box is a Dell Latitude CPx750J with this:

[root@dolphin root]# findchip -v
Found SMC FDC37N958FR Controller at 0x3f0, DevID=0x01, Rev. 1
     SIR Base 0x3e8, FIR Base 0x290
     IRQ = 4, DMA = 3
     Enabled: yes, Suspended: no
     UART compatible: yes
     Half duplex delay = 3 us

So clearly I'm using smc-ircc.o.

(Of course I'll try and reproduce in 2.5.44 tonight or tomorrow).


Thanks,
