lspci -vv with no wrapping in case that's easier to read
Are you using serial console? Would that be on the same port that is being closed in this instance? Please reopen this bug if: - it is still present in kerne 2.6.17 and - you can provide the requested information. I'm not using serial console, I haven't seen the bug with recent kernels so mebe as Adrian indicates the bug just got magically fixed. |
