Some questions: - Are you seeing the same issue with 3.6.x? - If you can reproduce this issue, could you paste the messages in dmesg when this happens? Do they resemble to the list corruption that was reported? - Do you see the same problem with 3.4? - Are you able to apply the patch Alan Stern posted in this thread earlier? We should really sort this out, but I unfortunately lack a system or setup that shows the bug. Thanks, Daniel
