Guru Meditation when booting with serial console in Linux

Reported by: magnusr Owned by:
Priority: major Component: VMM/RAW
Version: VirtualBox 4.0.0 Keywords:
Cc: Guest type: Linux
Host type: Windows


Setting the bootup console in the linux kernel to ttyS0 (i.e. by adding "console=ttyS0" to the boot command line) causes a Guru Meditation with the message "fatal error in recompiler cpu: Trying to execute code with memory type addr_code=00000000f000f020 addend=0000000031ce0000 at 00000000f000ff53. (iHandlerMemType=0x38 iMMIOMe mType=0x30)" in the log.

I'm running Ubuntu 10.10 with kernel 2.6.35-24-generic on the guest, and Windows XP SP3 and VirtualBox 4.0.0 r69151 on the host.

The crash is very similar to the one I reported as 8028, but I'm not sure whether they are the same or not.

  • Component changed from other to VMM/RAW

This bug will not happen if you boot your VM with VT-x enabled. The log file shows that VT-x is most probably there but not usable. The common reason is that VT-x was somehow disabled in the BIOS. Nevertheless this is a bug.

I just noticed I made a mistake: I added "console=ttyS0" as a Grub parameter, instead of appending it to the Linux boot command line. Putting it the correct place made Linux boot properly (so the problem is not as severe as I thought), but still there should not be a guru meditation even when doing it wrong, right?

Right. What happens if you boot the configuration which would induce the Guru meditation and decrease the guest RAM to 768MB?

Any change with VBox 4.0.4?
