Subject: HYP panic with 3.16-rc5, arm64 + 64k pages
Date: Thu, 17 Jul 2014 16:28:08 +0100 [thread overview]
Message-ID: <20140717152808.GO21153@arm.com> (raw)
Hi all,
If I try to spawn a kvm guest with kvmtool (not tried qemu) with a vanilla
3.16-rc5 kernel (same for host and guest) using 64k pages, I'm greeted by:
Kernel panic - not syncing: HYP panic:
PS:800002c5 PC:fffffe000042bd10 ESR:00000000bf000000
FAR: (null) HPFAR: (null) PAR: (null)
VCPU:0000020979e20000
CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.16.0-rc5 #4
Call trace:
[<fffffe000009642c>] dump_backtrace+0x0/0x130
on the host. The problem happens every time on Juno and the fastmodel.
Any ideas? Is anybody else seeing this problem? The limited guest output
is below.
