PCI IRQ routing table error

[knerr at cs.swarthmore.edu (Jeff Knerr)]

 Hello. I'm trying to get a 2.6 kernel to work with kdb, but I keep
 getting the above error on the BIOS splash screen, and then the
 machine's ethernet interfaces don't come up. 

 Here are the symptoms and some of the things I've tried:

  - first boot with 2.6.8 and kdb works (no error msg), but subsequent
    reboots give the IRQ error
  - if I use a kdb-patched 2.6 kernel, but without selecting the kdb
    option in "make xconfig", it seems to work fine (multiple reboots)
  - machine also works fine with plain 2.6.8 kernel (no kdb patches
    applied)
  - I've tried 2.6.8 and 2.6.11 kernels with same problem (I'm happy to
    try 2.6.14, if you think it will help)
  - we've successfully used kdb with 2.4 kernels on this machine
  - I searched google and this list's archives, but didn't see
    anything obvious

 If you've got any ideas for other things to try, please let me know. 
 Also, I've got lots of info (dmesg, lspci, etc), but don't know what
 will help debug this the fastest -- just let me know.

 Thanks.
