I've been running 2.6.27.4 with Matthieu's patches for the last day,
and it seems that the ep93xx-ohci driver has some issues. The bus is
resetting fairly regularly. This is problematic for me because I'm
using a usb flash device on /dev/sda1 as my root filesystem. Linux
doesn't seem to like it when the root filesystem spontaneously goes
missing.
I'm going to have to take a good look at this and see what I can discover.
On a slightly related note, my openembedded build for ts7260 has
almost gone smoothly.
Some problems that I've run into are:
1) I'm building a console-image, but for some reason things like
xrenderproto are being built ... I was under the impression that the
console image did not require X.
2) I'm currently stuck at shared-mime-info-native-0.51 - the build is
broken, but it could be because I'm not using any locales.
