Yesterday i tried to boot debian from sd-card with andy-tracking kernel
version 2d1d9ec0e2d009d0 and it didn't work very well.
First problem was that it seems to lack support for vfat partitions. I
use a 64MB swapfile which is on a vfat partition used by fstab while
booting. But at the point when activating the swap file it hangs and get
a timeout after 120sec and than do nothing.
After i removed the corresponding fstab line it boots up but the
hal-daemon didn't work anymore with the new kernel. Therefore some
things like the oevents from fso doesn't work anymore. This is maybe
related to the changed sysfs structure.
So at the moment i stay at the 2.6.24 openmoko kernel from the daily
build url as long as the userland tools use the old sysfs values.
