Subject: Fix for the APIC hangs in qemux86-64
Date: Wed, 13 Dec 2017 12:34:50 +0000 [thread overview]
Message-ID: <1513168490.19417.183.camel@linuxfoundation.org> (raw)
Hi Bruce,
https://bugzilla.yoctoproject.org/show_bug.cgi?id=12301
We've root caused the hangs we're seeing in qemux86-64 on our
autobuilder workers. We've identified a commit on 4.15-rc3 which fixes
the issue but backporting it to the autobuilder's host kernels will be
a pain.
As a workaround I'd like to enable x2apic on qemux86-64. Since that
works via MSRs it avoids the problem.
Would it be a big issue to set CONFIG_X86_X2APIC=y for qemux86-64?
Cheers,
Richard
