There are large stalls every now and again and looking at the kernel log, I'm getting lost interrupts on the ATA interface. This did not happen with the previous 2.6.28 kernel. Here's a sample from the log. [ 86.816503] ata1: lost interrupt (Status 0x58) [ 86.820070] ata1: drained 32768 bytes to clear DRQ.
