Subject: Unknown bridge resource


Hi all,

During boot, i got these two lines in dmesg:
Unknown bridge resource 0: assuming transparent
Unknown bridge resource 2: assuming transparent

What do they mean?


ps: I noticed these because they are written on the console even if quiet
mode is on. There was a patch for 2.4-ac, but it seems that it somehow
lost... :(

I just upgraded to 2.4.16 today and I noticed the same thing.

I'm using an IBM Thinkpad T20 if it makes a difference.

I'd gladly give more information it it helps.

If the pci id is not found (see drivers/pci/pci.ids), you'll get this
message. If you can supply the description, the maintainer is Martin
Mares <[email protected]>, see also http://pciids.sf.net/.
