64bit Linux guest randomly reboot Windows 7 - 32bit host

[PeterK]

Hello,

I tried to use several 64bit linux guests on Windows 7 32bit host. Uptime of 64 bit linux as guest is not longer as 4-5 hours. Host is reliable, no reboot except this issue. The issue is repeating on daily basis. 32 bit linux as guest is running fine.

Minidump is related to another guest, but I deleted this guest a few days ago

Is this a recent regression?

Replying to frank:

Yes, It is independent of any version Virtualbox, it is the same issue in newest 4.2.16.

Sorry, your answer does not make sense to me. I asked if this is a recent regression, which means that only the latest version is affected or perhaps the last two latest versions. But you wrote that you observe this version with any version of VirtualBox. So which versions did you test? Which is the first version where you observed this problem?

Ok, I used versions 4.2.6 ( first ), 4.2.14 and 4.2.16.

I experienced this on 4.2.14 also. Host: win7 32 Guest: ubuntu 12.10 64

yes ubuntu 32bit works fine. and 64bit mak win7 reboot suddenly. i find this is a old problem since bug tickets 9458, but no one can fix it.

I will mark this as duplicate of #11979. Please continue the discussion there. I provided also a test build which would help debugging the problem.
