Hi!
i notice a serious regression with 3.5 as Dom0 kernel (3.4 was rock
stable):
1st: only the GPU PCI Passthrough works, the PCI USB Controller is
not recognized within the DomU (HVM Win7 64)
Dom0 cmdline is:
ro root=LABEL=dom0root
xen-pciback.hide=(08:00.0)(08:00.1)(00:1d.0)(00:1d.1)(00:1d.2)(00:1d.7)
security=apparmor noirqdebug nouveau.msi=1
Only 8:00.0 and 8:00.1 get passed through without problems, all the
USB Controller IDs are not correctly passed through and get a
exclamation mark within the win7 device manager ("could not be
started").
Ok, but they do get passed in though? As in, QEMU sees them.
If you boot a Live Ubuntu/Fedora CD within the guest with the PCI
passed in devices do you see them? Meaning lspci shows them?
Yes, they get passed through:
pc:~# xl pci-list win
Vdev Device
05.0 0000:08:00.0
06.0 0000:08:00.1
07.0 0000:00:1d.0
08.0 0000:00:1d.1
09.0 0000:00:1d.2
0a.0 0000:00:1d.7
but *:1d.* gets a exclamation mark within win7...
sorry i have no linux hvm at hand right now to do a lspci.
Is the lspci -vvv output in dom0 different from 3.4 vs 3.5?
2nd: After DomU shutdown , Dom0 panics (100% reproducable) - sorry
that i have no full stacktrace, all i have is a "screenshot" which
i
uploaded here:

Ugh, that looks like somebody removed a large chunk of a pagetable.
Hmm. Are you using dom0_mem=max parameter? If not, can you try
that and also disable ballooning in the xm/xl config file pls?
i already have/had:
xen_commandline : watchdog dom0_mem=4096M,max:7680M
dom0_vcpus_pin
but autoballooning was on in xl.conf, i disabled it:
but still i get a panic as soon as domu is shut down:
(luckily i happend to press "enter" on the dmesg command exactly at
the right time to get the full stacktrace just before my ssh
connection died...)

[ 213.137611] Fixing recursive fault but reboot is needed!
seems like a ballooning thing - i will try to with only a "max"
setting, not a range ... stay tuned ;)
With 3.4 both issues were not there - everything worked perfectly.
Tell me which debugging info you need, i may be able to re-install
my netconsole to get the full stacktrace (but i had not much luck
with netconsole regarding kernel panics - rarely this info gets
sent
before the "panic"...)
Greetings
