fix for the problem that pciehp driver may not load
Please get this two line fix into the next RC build.
With regards to this specific patch/bug fix: Currently the hotplug code is not adhering to the ACPI 3.0 spec on how OSC should be used in conjunction with OSHP. The patch in Bugzilla 142454 fixes a bug in the hotplug driver so that the driver will be compliant with ACPI 3.0 usage model for OSC and OSHP. This patch has been Accepted upstream and tested at Intel. Any platform implementing ACPI 3.0 methods with OSC, will be vulnerable to this issue. Intel cannot provide any information with regards to specific BIOS implementations by OEM's. Consequently we can only comment on BIOS implementations that Intel is shipping. If any vendor ships a BIOS per the ACPI 3.0 spec. the hotplug driver is vulnerable to loading when _OSC denies control to native hot-plug. Intel's Harwich platform is shipping with ACPI 3.0 methods with in the next 3 weeks. Thanks, *EDC* Created attachment 112062 [details]
plaintext version of previous patch
This bug is currently *not* scheduled to be resolved in RHEL 4 Update 1. devel ACK for U2 I have a test kernel ready for testing, but we dont seem to have any ACPI 3.0 systems in house. Is there any way we could get some vendor testing done on on the some systems affected by this issue? If not, could we procure some hardware to test on? I can post a test kernel on people.redhat.com if needed Geoff - This is an old request. Please determine if Intel is still asking for this change, and that we have systems to test on. Trying to get a status update from Ed. xastir-2.0.8-4.fc26 has been submitted as an update to Fedora 26. https://bodhi.fedoraproject.org/updates/FEDORA-2017-06f5ed024f xastir-2.0.8-4.fc26 has been pushed to the Fedora 26 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2017-06f5ed024f |
