Subject: Re: [Xen-devel] [PATCH v2 00/48] xen: add core scheduling support
Date: Thu, 15 Aug 2019 11:17:39 +0100 [thread overview]
Message-ID: <c81b4a24-818d-7f1c-522e-f2120297569f@citrix.com> (raw)
In-Reply-To: <20190809145833.1020-1-jgross@suse.com>
Hi Juergen,
The latest round of testing revealed the following 3 Xen crashes:
1. vcpu_sleep_sync() <-- vlapic_init_sipi_action()
This was seen multiple times. It tends to happen on large Windows Server
VMs (>= 12 vCPUs).
https://paste.debian.net/1095844/
2. vcpu_sleep_sync() <-- vcpu_set_periodic_timer() <-- pv_hypercall()
This was seen on Sles 11.4 PV VM with 32 vCPUs and 6GB RAM
https://paste.debian.net/1095843/
3. ACPI S5: schedule.c#sched_slave()
This one was during shutdown again.
https://paste.debian.net/1095845/
There also were a number of Dom0 soft-lockups (together with RCU stalls)
but unfortunately our crashdump tool was a bit broken so full Dom0 kernel
logs were not captured this time.
And CentOS 5.11 suspend regression (as reported previously) is still
present.
Thanks,
Sergey
