This is an important but often overlooked point. My Myth box using XFS
would crash constantly when recording 3 shows while watching a fourth,
basically heavy IO. After a bit of frustration I found the notes about
using 8k stack kernels when using XFS and made the switch. It's been 4
months now and no crashes since.
XFS is generally rock solid. I have at least 100 servers using it for
the root fs for the past few years with no issues.
