This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. I tried to boot kernel-debug rpm with patch from bug#591083 on sonata-02 and it does not oops. Marking in depends on and taking this bug. Also, it seems that 'hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x000f0000' message goes away with update from bug#591083. Marking as duplicate of bug#591083. Please, reopen, if this issue can be reproduced with the latest RHEL 6.0 kernel. *** This bug has been marked as a duplicate of bug 591083 *** |
