lspci -vv with no wrapping in case that's easier to read

Comment 4 Russell King 2006-04-22 12:53:25 UTC

Are you using serial console?  Would that be on the same port that is being
closed in this instance?

Comment 5 Adrian Bunk 2006-07-10 13:24:02 UTC

Please reopen this bug if:
- it is still present in kerne 2.6.17 and
- you can provide the requested information.
