I'm trying to install Xen-unstable on a new machine. At first boot,
I'm getting a dom0 crash. The crash output is shown below. The
complete console log is attached.

I pulled from Xen unstable yesterday (bd376919f03a tip), and built it
simply using "make world". The machine has four Intel E5540
processors and 36GB of RAM. In the BIOS, I have VT-d disabled, and
VT-x enabled. Any suggestions on what steps I should take for
debugging this problem and getting dom0 to boot?
Thanks,
bryan

It looks like something has hit a BUG_ON. The first step is to try to
identify which one:
$ gdb vmlinux
(gdb) x/i 0xffffffff819067de
(gdb) x/i 0xffffffff81906d64
(gdb) x/i 0xffffffff81906166
should give a first clue.

It looks like its encountering a pfn (page number) that's greater than
the total number of pages given to the domain.
Aaah, 36GB memory. What happens if you configure
CONFIG_XEN_MAX_DOMAIN_MEMORY larger to match, or set dom0_mem to less
than 32GB?
(It shouldn't crash regardless, but it will confirm the diagnosis.)

Ok, so I tried setting dom0_mem to a variety of values less than 32GB.
I'm still getting a crash, but now it is more random. Basically, I'm
watching the boot process via a serial line, and instead of seeing the
dom0 crash output that I posted before, I'm simply seeing the output
stop, and the boot process hanging, in a different spot with each
boot. Removing the dom0_mem value beings me back to the behavior I
had before, where the dom0 crash output shows up reliably each time.

That's mysterious. My first thought is that this is a separate problem.
Is it ever stable? What happens if you set dom0_mem to 4G or less?
Is the console responsive when the kernel hangs? That is, can you type
"Ctrl-A Ctrl-A Ctrl-A" to get Xen, then enter debug keys? '0' (zero)
should dump the context for dom0 and give some clue about where it is dying.
Thanks,
J

I agree... and thanks for your help in diagnosing this issue.

It still crashes, even with 2G of dom0 memory.

Yes, this seems to work. Typing 0 dumped info for each of the cores
(i.e., 15 vcpu states). I've attached the output.

Could you map the RIP values to a symbol with gdb? From a quick look,
it seems that most or all of the cpus are at the same place. No, vcpu 8
is doing something else at least.
What happens if you boot dom0 with fewer cpus?
Do you have CONFIG_PARAVIRT_SPINLOCKS enabled?

It's the same as starting dom0 with 4G - 32G of memory, just freezes
at a different place in the boot each time.

I tried adding "maxcpus=1" to the linux kernel line in grub. I used
this in conjunction with the "dom0_mem=2G" option for xen. Dom0 still
crashes the same as without the maxcpus option.
Just for kicks, I tried a few other options...
* setting mem=4G with dom0_mem=2G seemed still resulted in random dom0 crashing
* setting noapic resulted in a consistent crash within Xen:

778/32 = hypercall 24 = vcpuop. Probably idling.

That's almost certainly a kernel panic of some kind. Working out where
it came from will be rather tedious: you need to look through the stack
dump to find code-ish looking addresses then x/i them (they'll be the
same basic format as 0xffffffff8xxxxxxx).
(I really need to work out why they tend not to get printed.)

That shouldn't happen. Sounds like it might be fall-out from the recent
interrupt changes in Xen. Did you supply "noapic" to Xen, dom0 or both?

Nice ;-) I'll let you know what I find out.
