Package: linux-image-2.6.18-2-xen-vserver-686 Version: 2.6.18-5 I use Debians 2.6.18-5 kernel sources to build my own xen-vserver kernel image for my Sarge XEN/vserver system. The problems looks like the following: DomUs with pass-through PCI devices seem to have problems with interrupt handling like the following dmesg excerpt shows (from domU named 'trustedvserver'):
irq 16: nobody cared (try booting with the "irqpoll" option) [<c014f4aa>] __report_bad_irq+0x2a/0x90 [<c014f5e7>] note_interrupt+0xb7/0xe0 [<c014ebc8>] __do_IRQ+0x138/0x150 [<c0106ce8>] do_IRQ+0x48/0xa0 [<c0257ee3>] evtchn_do_upcall+0x93/0x110 [<c0105285>] hypervisor_callback+0x3d/0x48 [<c01099f7>] raw_safe_halt+0x27/0x60 [<c0102ad3>] xen_idle+0x23/0x40 [<c0102b73>] cpu_idle+0x83/0xd0 [<c0406a0f>] start_kernel+0x1cf/0x230 [<c0406300>] unknown_bootoption+0x0/0x1e0 handlers: [<c02aead0>] (usb_hcd_irq+0x0/0x70) Disabling IRQ #16 (This is the onboard USB controller with an usb sound apdater attached to it) The bug also seems to kill the kernel NFS server (it doesn't respond after such a kernel oops and the domU has to be restartet). Or this dmesg excerpt is from another domU called 'router' with 2 NICs (a 3Com 10/100 (ethdsl) and an Intel e1000 (eth0)): NETDEV WATCHDOG: eth0: transmit timed out e1000: eth0: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex NETDEV WATCHDOG: ethdsl: transmit timed out ethdsl: transmit timed out, tx_status 00 status e601. diagnostics: net 0ccc media 8880 dma 0000003a fifo 0000 ethdsl: Interrupt posted but not delivered -- IRQ blocked by another device?

A third domU (called 'dmzvserver)' without any physical devices does not suffer from this problems. I'm using XEN 3.0.3 (no Debian packages, the stock XEN release tarball). When booting the domUs with my previous 2.6.16.27 kernel (for XEN 3.0.2) there is no problem although I have to use kernel 2.6.18.2 for dom0 (XEN 3.0.3 doesn't want to boot dom0 with my 2.6.16.27). I also suffered from this problem with the 2.6.18-3/2.6.18-4 sources with patch mentioned in #397281 applied.
