Xen3 DomU spins 100% busy during console access


I was in vim in insert mode and just pasted a large selection into the xenconsole - instant busy lockup. Once I figured out what caused it I was able to repeat this 5 out of 5 times.

I tried this with small simple lines and was never able to lockup the console. I have however managed to to cause this lockup by pasting less than 1KB of data, and then pasting more in small pieces until it exceeds 1KB. I have no idea why 1KB might be a magic number but perhaps its a hint.

lastly I also had a similar lockup by just connecting to the console with 'xm console test1' no copy paste with the mouse at all.

this is an intel HT core, both Dom0 and DomU running 4.99.4 from Nov28 daily builds.
