Sorry for not reacting - I didn't get any notice from bugzilla.. (?)
I've just migrated to the brand new 2.6.27.19 kernels in both Dom0
and DomU and I'm happy to report that everthing seems to work now
without a hitch! I can restart the domain, attach/detach USB hardware
while running, I see the interrupts, IRQ sharing seems to work, too.
For reference here is the /proc/interrupts from Dom0:
CPU0 CPU1
1: 12709 0 Phys-level i8042
8: 0 0 Phys-level rtc0
9: 0 0 Phys-level acpi
12: 2059 0 Phys-level i8042
16: 269237 0 Phys-level pata_jmicron
18: 108412152 267107 Phys-level eth2
19: 5048870 16324 Phys-level ahci, ata_piix, ata_piix
20: 2368670 24503 Phys-level eth1

1282: 0 0 Dynamic-level callfunc
1283: 2062 3101 Dynamic-level call1func
1284: 9144 7538 Dynamic-level spinlock
1285: 3061 1326 Dynamic-level xenbus
1286: 0 0 Dynamic-level console

1293: 768974 227531 Dynamic-level vif2.0
1294: 116993 19219 Dynamic-level vif2.1
NMI: 0 0 Non-maskable interrupts
RES: 177959 109594 Rescheduling interrupts
CAL: 2062 3101 function call interrupts
and from the DomU:
CPU0
16: 0 Phys-irq-level uhci_hcd:usb1
18: 108518274 Phys-irq-level uhci_hcd:usb5, ehci_hcd:usb6
19: 0 Phys-irq-level uhci_hcd:usb4
21: 0 Phys-irq-level uhci_hcd:usb2
23: 24371800 Phys-irq-level uhci_hcd:usb3, ehci_hcd:usb7
256: 66495050 Dynamic-irq-level timer0
257: 0 Dynamic-irq-level resched0
258: 0 Dynamic-irq-level callfunc0
259: 459 Dynamic-irq-level xenbus
260: 4100 Dynamic-irq-level xencons
261: 513191 Dynamic-irq-level blkif
262: 1002777 Dynamic-irq-level blkif
263: 29691447 Dynamic-irq-level eth0
NMI: 0
IRQ 18 is shared and works ok, IRQ 23 is unique to the DomU and works as well.
Thanks again for your support!
Cheers,
Wolf
