This may well be a bug in Firefox or some other userspace component, however it is serious enough that the kernel developers ought to know about it.

I tried several times to download a Linux kernel tarball; each time Firefox reported that the entire file was downloaded, however the file in my filesystem was quite a lot shorter than the size reported at kernel.org.

I speculated that Firefox had a caching bug, and so closed all my tabs one by one, then closed the window. The file was still incomplete.

I launched a new Firefox, retried the download, still incomplete.

I shut down my box, booted it, then was able to download successfully.

Perhaps the problem has something to do with Hibernate; I do know there were some problems in the past with hibernating my motherboard, a SuperMicro X7DWA-N. Under a much earlier kernel, with Fedora 7, while I could go into and out of hibernation, after coming out the networking did not work.

With my present Linux Mint Cinnamon 17.1 64-bit install, I've been using hibernation quite a bit.

I am just now seeing some evidence that I may have a more serious problem, perhaps I have bad memory or something. I'm going to run Memtest86.

I'm using an AMCC3ware 9690-SA 4-disk RAID5, with battery backup so as to enable write caching.

Can you attach here content of /proc/mounts, df, and /var/log/messages from around the time when the problem happened? Also what kernel version do you run (uname -a).
