After getting a 2014.01 u-boot built with Xuebing's patches, I found
that 10-STABLE hangs at some point after the kernel has configured the
usb hubs. The abbreviated console log is below; since the kernel had
booted, I was able to get a stack trace (also included below).
However, the patched u-boot works ok with 11-CURRENT. Looking at the
patches, it wasn't immediately apparent as to what exactly enables the
1Ghz mode ... maybe it's just having a newer u-boot?
Is there something specific in 11-CURRENT that enables/supports the
1Ghz operation?
Thanks!
