Resending this since all I'm getting is silence and it's quite a problem for this box. I did a few google searches and aparently I'm not the only one having this problem - I see reports going back for years, but no solutions. I've got heaps of dmesg output if wanted/needed, I'll test patches, suggestions etc. Any ideas people?
