Subject: [PATCH 0/2 v2] x86: Improve secondary CPU bring-up process robustness
Date: Tue, 19 Jun 2012 14:14:19 +0200 [thread overview]
Message-ID: <1340108061-5128-1-git-send-email-imammedo@redhat.com> (raw)
Reproduced mostly in virt. environments, where physical CPUs are shared
beetween many guests and on overcommited host guest's CPUs may stall
and lead to master CPU 'canceling' CPU bring-up. But in reality being
onlined CPU continued to boot and caused hangs when onlining another CPU.
Now, I'm trying do fix issue a bit earlier. I hope it's better than
the first attempt: https://lkml.org/lkml/2012/5/9/125
Please review.
