Message-ID: <20100319152502.GA19472@phenom.dumpdata.com> (raw)
For the fun of it, I tried to boot 2.6.34-rc1 as PV guest and it
just hangs (1 CPU, 512MB). xenctx shows this:

I haven't taken a look any further than that, has anybody seen this
or maybe is itching to dig in the kernel to figure this out?
