Bug Description
This problem affected me in 12.04 as seen here (Problem behaves the same) : https:/
Basically the error output starts and after around 45 minutes of errors the whole system freezes. Complete freeze that I have to force reboot.
I upgraded to Ubuntu 12.10 Beta2 since the problem was mentioned to be solved in Kernel 3.4 as seen here: https:/
As you can see in the information provided, I am using the 3.5 version of the Kernel and the problem persists and it happens at least 2 to 5 times daily. It happens more if I watch a youtube video, downoad through torrent or try to connect to any online bandwidth consuming site or app.
Here is a couple of the error logs from syslog:
DMA: Out of SW-IOMMU space for 490 bytes at device 0000:03:02.0
DMA: Out of SW-IOMMU space for 517 bytes at device 0000:03:02.0

Looking at the PCI ID I did a sort|uniq and found the following other network devices giving the same problem:
03:02.0 Network controller: Ralink corp. RT2800 802.11n PCI
03:00.0 Network controller: Broadcom Corporation BCM4321 802.11b/g/n (rev 01)
I have 4 network cards:
product: 82579V Gigabit Network Connection (Internal Intel DZ68DB Motherboard Wired Card)
product: BCM4321 802.11b/g/n (Broadcom Chipset, Linksys WMP300N http://
product: RTL8169 PCI Gigabit Ethernet Controller (PCI Realtek Wired Card)
product: RT2800 802.11n PCI (Wifi-N Ralink 2 Antennas)

Testing Kernel 3.6 from here: http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v3.6-quantal/ and it has been at least 10 hours with no problems. With Kernel 3.5.x the problem appeared at least every 2 to 3 hours. Sometimes almost 4 hours.
Will keep checking.
