Description Dean Nelson 2009-07-28 15:12:42 UTC

Description of problem:

PCI drivers that implement the struct pci_error_handlers' error_detected
callback should return PCI_ERS_RESULT_DISCONNECT if the state passed in is
pci_channel_io_perm_failure. The igb network driver does not do this.


Additional info:

The solution will be to backport an upstream commit authored by
Alexander Duyck <alexander.h.duyck>. See the following URL for details.

Comment 1 Dean Nelson 2009-07-31 21:46:52 UTC

My test kernel rpms have been updated to include a patch for this bugzilla.

http://people.redhat.com/dnelson/#rhel5

Please test them and report back your results. Without immediate feedback
there is a good chance this or any other fix for this driver will not be
included in the upcoming update.

Needs to be in MODIFIED to get added to the errata, at which point, the errata tool will flip it to ON_QA. Just need that 5.5+ flag (and maybe the exception flag+, not sure) and I can add it.
