Hi,

I've also the same problem since about one year and just opened a bug here. Now
with some other search patterns I've found this, so mine is a clone *sorry*

I've found a patch which fixed the problem for me: see bugreport #16471

https://bugzilla.kernel.org/show_bug.cgi?id=16471

regards
Patrick

patch to disable 64 bit dma on systems with PCI (only) adapters, and more than 4GB ram, committed to net-next, should already be in linux-next, and will be in 2.6.37-rc merge window.
