Comment 54 for bug 401126

@ Fiat1100d. Sorry to hear you still have problems.

Interestingly I just looked at dmesg and it seems I'm also getting some dmesg errors - though not the same as you:-
 6123.160234] ===========rtl8192se_update_ratr_table: ff5
[ 6123.160243] ===>set to B/G mode

However, the device itself seems to be working perfectly. In fact, I just done a 300MB upgrade to my system. And I been listening to internet radio almost all day, without issue, via http://www.garfnet.org.uk/internetradio

And I'm sending this message from the very same machine.

Seems the driver is still a bit buggy though. There may also be a separate kernel problem in your case, because Googling this it seems the SW-IOMMU issue seems to be fairly common with other cards too, from kernel 2.6.15 onwards.

Which Kernel version are you using? Is it 32 or 64 bit?

Best wishes, G.
