Guru meditation freeze with linux 2.6.21 kernel -> fixed in SVN/1.5.2

[jamesbond]

CPU: Core Duo
RAM: 2 GB
Host OS: WinXP SP2

Guest OS: Puppy Linux 2.17beta - kernel 2.6.21
Emulation freeze during boot. Vbox still responds, I can close window and restart a new emulation session.

The summary error from vbox.log is as follows:

Note that earlier version of the distro (2.16.1 using kernel 2.6.18) works fine.

I'm experiencing the same error. I reported this some time ago in the forum, so far no resolution found.

I'm using a debian installation, kernel version is 2.6.21.5. I did not try any other versions.

Trying to narrow the problem down, I compiled different kernel configurations. So far it seems that SMP-kernels work fine, UP kernel don't. For most configs the freeze is _reproducibly_ while populating /dev (think second task after init started). I got one config, where the freeze is reproducibly while sshd is starting (i.e. much later).

Same problem here:

Host: Pentium D CPU 2.80GHz 2GB RAM Linux 2.6.21-gentoo-r3 x86_64 with SMP Virtualbox 1.4.0 OSE

Guest System is a 32bit Linux (Gentoo). Kernels with CONFIG_SMP=y works fine, using CONFIG_SMP=n makes the machine freeze during init. We tried Linux 2.6.21 and 2.6.22 => same result.

Guest kernel config (the buggy one without SMP)

...Never seen this yet - but anyway

Nice to see that there are some old Amiga loving devs around there! I always loved it! (And if I've some spare time I'll boot my A1000 again to see a Guru Meditation)

Adding a me-too. Running VBox under Pentium D 950. Gentoo runs fine with kernel 2.6.20. Just compiled kernel 2.6.22 using the same settings as the earlier kernel, specifically SMP=no. 2.6.22 starts to boot but hangs after this line:

"Mounting devpts at /dev/pts"

I recompiled 2.6.22 with SMP turned on, and now it boots up fine. So this seems to definitely have something to do with a non-SMP kernel.

See 386 for a description of the same thing happening in a Debian guest.

Replying to guyr:

I recompiled 2.6.22 with SMP turned on, and now it boots up fine. So this seems to definitely have something to do with a non-SMP kernel.

BTW - the exact same non-SMP kernel binary boots okay with VMware, qemu, and bare-metal. So it has got something to do with vbox's non-SMP emulation.

Same problem still happens for 1.5.0.

[benjamin9999]

same problem here, 1.4.0 and 1.5.0. 2.6.20 works, 2.6.22 does not. dies in a similar place in gentoo startup as described above.

[Sander van Leeuwen]

Fixed.
