This system has been available since late 2009, and the I/O subsystem has not changed since its introduction. One reason we haven't seen this problem until now is that RHEL6 (kernel 2.6.32) is the only supported Linux operating system for this platform, and this problem surfaced in 2.6.34. I found this problem because I recently started thinking ahead to RHEL7 and so started trying to work with recent Fedora releases. It looks like from now on I'm going to be banging on upstream kernels as soon as they come out so we catch this sort of thing sooner... --jim -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
