Public bug reported: Binary package hint: ubuntu-xen-server
I had been commenting on Bug #135818, however it is marked as fixed. This issue seems related, but is not identical: //**********// Alvin Cura wrote on 2007-11-05: (permalink) I'm afraid I'm still seeing this bug. Or something similar. I did not get a kernel panic, but my network died and stayed dead. I was, however, able to reboot.

Problem is persisting, even with a different NIC (although also a Realtek, this one a PCI card instead of the onboard): syslog:Nov 11 23:22:17 xen1 kernel: [ 8113.207809] PCI-DMA: Out of SW-IOMMU space for 7222 bytes at device 0000:03:05.0 syslog:Nov 11 23:22:40 xen1 kernel: [ 8136.691486] PCI-DMA: Out of SW-IOMMU space for 7222 bytes at device 0000:03:05.0 syslog:Nov 11 23:23:17 xen1 kernel: [ 8173.209884] PCI-DMA: Out of SW-IOMMU space for 7222 bytes at device 0000:03:05.0 syslog:Nov 11 23:24:17 xen1 kernel: [ 8233.214080] PCI-DMA: Out of SW-IOMMU space for 7222 bytes at device 0000:03:05.0 syslog:Nov 11 23:24:32 xen1 kernel: [ 8248.385552] PCI-DMA: Out of SW-IOMMU space for 7222 bytes at device 0000:03:05.0 03:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
