I just started testing my new Beagleboard (Rev C4) and installed
Angström (demo-image-glibc-ipk-2010.3, U-Boot 2010.03). Two things
I've learned so far:
1. U-Boot stops at "I2C: ready" or the system boots up until the
kernel starts panicking:
[ 27.140289] hub 2-2:1.0: USB hub found
[ 27.144500] hub 2-2:1.0: 4 ports detected
[ 27.148559] Unable to handle kernel NULL pointer dereference at
virtual address 00000014
...
[ 27.810058] ---[ end trace 141129ef1c20ddd9 ]---
[ 27.814758] Kernel panic - not syncing: Fatal exception in
interrupt
I am actually powering the Beagleboard by mini-USB (HS OTG) which
shares my self-powered usb-hub (F5U701-BLK) with a keyboard, a mouse
and a USB-to-mini-USB connection back to the EHCI HS controller.
If I unplug the hub before booting and plug it in again - after I see
the login screen - everything works flawlessly.
2. No sound output until I unchecked "Automatic Volume (rising)" in
the Sound Setup. Give it a try.
best,
Armin

Upgrade your X-loader properly to 1.4.4ss to use U-boot 2010.03

Use external power, i believe this is a known issue being worked on
with Angstrom's kernel.
