I have an ao522. In my case, the problem is with the wireless support.
When I connect to my wireless, shortly after (immediately or sometimes
after a delay) the system locks up hard. No X updates (clock on desktop
does not advance). No response to keyboard or mouse or soft poweroff.
This is a fresh install of 11.04 i386, with updates.
When it locked up for the first time, I installed the proprietary WL
driver. It still locks up.
Here's what lspci -vnn says about the wireless:
07:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n
Wireless LAN Controller [14e4:4727] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:0510]
Flags: bus master, fast devsel, latency 0, IRQ 19
Memory at f0100000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: wl
Kernel modules: wl, brcm80211
** Package changed: ubuntu => broadcom-sta (Ubuntu)
