OS6 now works on x86 Legacy WARNING: NO NTGR SUPPORT!
Update: It is now unofficially possible using NTGR images to update legacy hardware to os6.X See Post #3, for directions to install 6.2.1 on x86 Ultra and Pro Models. (ARM NOT SUPPORTED by this OS) ...
mdgm and I have decided that its time to lock this thread. So please do post any new OS6 on Legacy issues on their own threads.
Less, but I still had to restart the device three times (hard reset via power cycle). I've nice'ed and ionice'ed sabnzbd and sickbeard in hopes of relieving it. It works to some extent. Nowhere near the performance that I had on OS4 though. I was able to download using sab at a comfy 12.5MB/s without slowing the system down one bit, combined with a running par2 or unrar job. Now, I'm lucky to make 6MB on an otherwise idle system. When attempting a download of a 100mb.bin file, the speed is good (10MB/s) and no noticeable load. It really does seem to be a problem of a lot of small files being written, and IO locking up.
Unfortunately, I can't run iotop since the kernel is too old or not configured for it, so I can't really track down the issue.
To illustrate, here's an iostat while sabnzbd is downloading:
