Hi,
recently I got all sorts of problems trying to reconfigure my 3.0-current
system. They seem all to be related to the PnP code in i4b. Here is my
horror story in detail:
I just wanted to remove some unused options and drivers in my bloated custom
kernel. After removing them, the machine hung just before the
Probing for devices on the ISA bus:
(just after the PnP probe, but the kernel didn't find "isic1").
Only after re-enabling device pcm0 (Luigi's sound code), the PnP probe
succeded (the isic1 device showed up), just to the point where the machine
rebootet immediately after displaying
Probing for devices on the ISA bus:
I re-enabled some more options and devices and found out I had to enable
*both* IPFIREWALL and IPFILTER to make the machine work again (I haven't tried
IPFILTER alone, though, because I need the divert-sockets)
If I compile an working kernel as ELF, the boot process stops again during
the PnP probe.
Therefor I hacked the i4b source. The patch below allows you to use the
winspeed card without the PnP code. You can now configure your card as usual:
options "SEDLBAUER"
device isic0 at isa? port 0x100 net irq 10 flags 0x18 vector
isicintr
(no I4B_PNP)
Beware: The port and irq value aren't really probed.
You may have to boot "-c" and set the PnP configuration manually:
pnp 1 0 enable os port0 0x100 irq0 10 (if this is the only PnP card)
Did anybody else had similar problems with a recent -current and PnP ISDN
cards?
Daniel
