Just last week I was running staging to test pvscsi on this HP ProBook
6555b, since around Wednesday I think. But todays staging fails to boot.
So I started a bisect in xen/, but every attempt to boot xen.gz results
in a hang at the same place. Even going back to the state of 4.5.0.
Any idea what may cause this hang, and how I can debug it further?
Without sync_console it barely gets past "SVM: Supported advanced features:",
on VGA it always gets to the "PVH mode not supported" line.

This smells like an external factor. Have you changed compiler in that
time, altered the BIOS settings or updated the firmware?
Are you able to use the console debugkeys once it gets into this state?

Nothing like that. I carried the thing around for a week, and started to
run Xen during that time. Since Saturday its back in its usual place and
position. I think I ran Xen on that day, but the bootlogs have no
indication if I really did.
Yesterday after some poking around in the firmware and running the
selftests I was able to boot Xen again. But today it failed again.
> Are you able to use the console debugkeys once it gets into this state?
No, it does not react to anything. I think a triple CTRL-A and 'h'
should print the help text? I see the cursor blinking on the display,
not sure if thats an indication that Xen is still alive.

The keyhandlers should be set up by the point, although most of them are
deferred to tasklets. Try the 'i' key which will run synchronously in
serial rx irq context.

Key handlers are only available via serial, I think, and not VGA which
it sounds like what Olaf is looking at.

This laptop has a serial port, and thats what I used to grab the output.
No reaction there. Just today I noticed the blinking cursor. Will
continue to poke this as time permits.

You can also use the USB EHCI debug port. It works great on laptops.

These are fan devices. Guess I have to open it some day and see if there are
any cable issues. Have to do it anyway, after HP sent it back from repair they
did not wire up the CDROM device.

xen_commandline : console=vga,dbgp dbgp=ehci1 loglvl=all iommu=verbose,debug
Which is because:
[root@x230 konrad]# lspci | grep Enhanc
00:1a.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset
Family USB Enhanced Host Controller #2 (rev 04)
00:1d.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset
Family USB Enhanced Host Controller #1 (rev 04)
And while both of them have an USB debug port (the first one), it looks
to tied to the docking station. The other is the one I can plug the
USB debug device.
Naturally since this is an USB debug device you need to get an special
$99 USB debug device (Google for it).
The other end of the USB device goes in another machine on which I do
screen /dev/ttyUSB0 115200 cs8
And I see the whole Xen console output.

It boots with "maxcpus=1", so the "Brought up n CPUs" line is whats missing.
Even the RELEASE-4.0.0 tag fails to boot, have to check if maxcpus= will
help there as well.

No, but are you able to at least dump the status of the registers?
