Bug Description
I just setup Kubuntu Raring on my notebook yesterday and things seem to work fine except for samba/cifs. Sill using SMBv3 I can't transfer large files anymore. At about 100MB transfer the kernel log gets filled with those error messages:
DMA: Out of SW-IOMMU space for xx bytes at device ....
and the network becomes completely unusable. Only solution I have found was to reboot the system and at shut down, you also keep getting tons of those errors. However when using SCP or rsync over SSH there aren't any problems.
My network card: 05:00.0 Ethernet controller: Atheros Communications Inc. AR8151 v2.0 Gigabit Ethernet (rev c0)
Meanwhile I reverted back to using the 3.5.0-27 kernel from Quantal - that one has no issues.
