Emulator won't load 2.2 but will load 2.3

On a Windows XP system, using Eclipse 3.5, JDK 1.6.24, and the Android R10 SDK.

Like a number of others, I'm unable to get the emulator to load the home page, but this is happening only for the 2.2 image. I am able to get the emulator fully loaded and running with 2.3. I've tried waiting for a long period of time (I think 2 hours is more than enough), killing and restarting the adb server, etc.

The emulator is stuck in a reboot loop caused by the serverthread throwing a SIGSTKFLT signal. This is a signal that's not actually used by current versions of Linux but is sometimes thrown by app's to signal an application error. Unfortunately, there's no specific error message (at least that I can find) to indicate why the signal is being thrown. The pertinent part of the logcat is:

And then the whole thing runs through in an infinite loop of start/fault/dump/restart. I don't think this is a showstopper for me as I can target in 2.2 and run 2.3 in the emulator till it's time to load on a real 2.2 device. But it's something of an annoyance.

UPDATE

I was able to partially load froyo outside of eclipse using the command line. Starting it with "emulator @froyo -no-boot-anim -logcat '*:v'" it loaded as far as showing the top bar with the battery indicator. Omitting the logcat switch it started as far as showing the background before crashing. This looks more and more like a timing issue.

This is also now just happening on a laptop. When installed on one of my desktops Froyo comes up and is working. Both have the same speed CPU, but the laptop is a P4 2.2ghz with 1G memory and the desktop is a dual Xeon 2.2 with 2Gb memory. Both have similar application and service loads.
