I have the same problem, also reported previously on different kernels , lucid onwards. I am now on maverick, and same problem, though not as frequent. I have installed backport of 2.6.37, and getting the same problem. uname -a => Linux pio 2.6.37-020637rc2-generic #201011160905 SMP Tue Nov 16 09:08:47 UTC 2010 x86_64 GNU/Linux
It also affects USB devices, and can sometimes cause all USB devices to fail. I have pata_via module I can reproduce effect by loading system, ethernet transfers, tv tuner working and running virtualbox. At other times, it sometimes fails with practically no load on system. /var/log/messages=> Dec 1 14:18:49 pio kernel: [14688.080072] ata2: lost interrupt (Status 0x51) Dec 1 14:18:49 pio kernel:
