SMC-IRCC broken? 2.4.5-pre4 / -ac5+

SMC-IRCC broken? 2.4.5-pre4 / -ac5+

[Pawel Worach]

Good afternoon!

Between pre3 and 4 (also somewhere in the middle of the -ac series)
the smc-ircc and/or irda subsystem went broken (at least for me).

The kernel stops while booting at:
TCP: Hash tables configured (established 16384 bind 16384)
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
SMC IrDA Controller found; IrCC version 2.0, port 0x118, dma=3, irq=3

The next message shuld be (in 2.4.4):
IrDA: Registered device irda0

It looks like it's some kind of loop, because the CPU fan starts running
at full speed.

This is on a Fujitsu-Siemens Lifebook S-4546

grep ^CONFIG_ .config | remove unimpotant lines:
CONFIG_IRDA=y
CONFIG_IRLAN=m
CONFIG_IRNET=m
CONFIG_IRCOMM=m
CONFIG_IRTTY_SIR=m
CONFIG_IRPORT_SIR=m
CONFIG_SMC_IRCC_FIR=y

gcc:
(gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81))

More info? just ask!

ps. I'm not on the list so please cc.

IRDA compiled in  ? If so is it ok modular . It sounds like yet another boot
ordering wonder

If I use it as a module it won't load
It says 'Device or resource busy'. (and yes i'm using the same io/irq
params as detected during bootup while compiled in).

That's why "half" of the irda subsys is compiled in. The protocol
code is modules.

Just got it working as a module in -ac5, but still the kernel frezes
if I use it compiled in. -ac6 makes no diff.
