Resend: Sorry copy and pasted a wrong mailadress for the xen-devel list.
Hi Boris / Juergen,
This morning i got this dom0 kernel crash (it occurred sporadically
before (during 4.11), but i didn't have serial console enabled at that
time so i had no stacktrace, only sporadic reboots).
It's running on an AMD phenom X6:
Kernel 4.11.0-rc7 with as latest commit:
94836ecf1e7378b64d37624fbb81fe48fbd4c772.
Xen-unstable with as latest commit:
94836ecf1e7378b64d37624fbb81fe48fbd4c772.
If you need more info please ask, testing will be difficult as i don't
have a clear testcase and
it can also run for days without trouble.

Sander

Any cpu onlining/offlining during the test?
XEN_IRQ_WORK_VECTOR vector is allocated for all PV VCPUs in
xen_smp_intr_init() so it's somewhat odd that we fail to find it.

If you can keep console while running this, can you add these changes
and see if we ever unbind the work vector (you can even add dump_stack()
in __unbind_from_irq() for good measure)? (I added HHH for easy grepping)
Also do 'grep -i work /proc/interrupts' so that we know which IRQ the
work interrupt is.

Hmmm i f*cked up and accidently compiled a tree with "for linus 4.12"
pulled in and ran that instead of the vanilla 4.11-rc7 (while not naming
it "xen-next" as i normally do.
So 4.11-rc7 is most probably fine, sorry for that noise.
Since your patch doesn't apply the smp part is changed. Seems the
problem somewhere lies in there (Vitaly's patches, general x86 stuff
being pulled in to base that on). I can see if i can adapt the patch
to for linus 4.12 and retest, instead of waiting for it to be pulled in
into Linus his tree in the next merge window.

Thanks. If you just could translate those again to symbol+offset?
And the suspicious addresses on the stack as well:
ffffffff81023bfd
ffffffff81cc4620
ffffffff81ccb060

Hah, missed that one: the system is just repeating the (saved) boot

So we are somewhere between console_init() and smp_init(). Probably
at kernel_thread(kernel_init, NULL, CLONE_FS); in rest_init().

Subject: [PATCH] x86/amd: don't set X86_BUG_SYSRET_SS_ATTRS if forced to zero
When running as Xen pv guest X86_BUG_SYSRET_SS_ATTRS must not be set
on AMD cpus. Xen will disable this via setup_clear_cpu_cap(), so test
cpu_caps_cleared to not have disabled this bug.
