[11:51] <React0S> it started right after opera problem
[11:52] <cgutman> is it just a stock vbox virtual machine with no config changes?
[11:52] <React0S> yes
[11:52] <React0S> windows xp profile
[11:52] <React0S> 256 ram
[11:53] <cgutman> IDE hard disk?
[11:53] <React0S> and the only - seriall port
[11:53] <React0S> yep
[11:56] <cgutman> I can't replicate it
[11:56] <React0S> vbox version?
[11:57] <cgutman> 4.2.0 RC2
[11:57] <React0S> mine is 4.1.18
[11:57] <cgutman> what's your host CPU?
[11:59] <React0S> E6550
[11:59] <React0S> core2duo
[11:59] <cgutman> hmm, ok so no MMU virtualization
[12:00] <cgutman> sometimes VT-x makes things weird
[12:00] <cgutman> plenty of races too
[12:00] <cgutman> I could try on one of my older rigs
[12:00] <cgutman> this machine is a 3770K
[12:01] <React0S> how mutch time would it take
[12:01] <React0S> it seems to me it also happens on my Phenom I x3
[12:02] <cgutman> same level of hardware virtualization support there
[12:02] <cgutman> I tried disabling nested paging and it still works here

[12:21] <Caemyr> can you regress-test it?
[12:21] <React0S> it is since begining of Ion series of commits
[12:22] <Caemyr> we need a bug report
[12:22] <React0S> but i cant do it closer because of other bugs presented by ion )
[12:22] <Caemyr> the problem is that builders do not reproduce it
[12:03] <React0S> so when are you able to test?
[12:04] <cgutman> still boots even with VT-x totally disabled
[12:04] <cgutman> I can probably do it sometime later today
[12:05] <cgutman> see if you can find anyone else who can replicate your isue
