[irda-users] IrDA discovery broken in Linux 2.4.19 ?

Hi there,

my Palm Vx does register IrDA activity from a FSC Lifebook E6624 (SMSC=20
I/O chipset) but Linux IrDA in 2.4.19 does no longer seem to discover
the Palm (/proc/net/irda/discovery without entry). This used to work=20
fine before with kernel 2.4.17/18. The Palm Vx syncs fine with 2.4.19=20
and an Actisys 210L motherboard dongle connected to a desktop though.
Beaming from the Palm device works in Win 2000 on the laptop, so the IR=20
hardware should be o.k.

Second serial port configured as IrDA in BIOS (verified in Windows as well):
/dev/ttyS0 at 0x03f8 (irq =3D 4) is a 16550A
/dev/ttyS1 at 0x02f8 (irq =3D 3) is a 16550A

cat /proc/interrupts:=20

The modules load fine:
