This bug is not new - it has existed for a long time. And - the bug is not
restricted to the RedHat-rpm. (I have earlier tried to compile v1.19 myself
- and the same bug is there).

It affects many ISA-PnP isdn-cards, and the bug is well known by people
using these cards. I have a Teles 16.3C.

Before setting up the isapnp cards I have this output from "cat
/proc/ioports":

0000-001f : dma1
0020-003f : pic1
0040-005f : timer

d8072000-d807201f : Intel Speedo3 Ethernet

Then: 
"pnpdump -c > /etc/isapnp.conf" and:
"isapnp /etc/isapnp.conf"

results in this error message:

The first card is a SB-AWE64 Sound card - the second is the isdn-card.

Here is some lines from the /etc/isapnp.conf starting with line 386:

  (IO 0 (SIZE 2) (BASE 0x0580) (CHECK))
#       IRQ 3, 4, 5, 9, 10, 11, 12 or 15.
#             High true, edge sensitive interrupt (by default)
  (INT 0 (IRQ 3 (MODE +E)))

As a solution - to get the card to work - I have to remove the "(CHECK)" in
the line with the io-address (386). Then everything is working properly!:
