[Bug 584143] Re: qemu fails to set hdd serial number

2010-06-02 Thread Luiz Capitulino
Bug exists in both current master and stable v0.12.4, but the suggested
fix doesn't leave room for the null terminating byte, will submit
upstream a better version.

[Bug 246067] Re: Kernel panic during boot in VirtualBox with kernel 2.6.26.*-generic

2008-09-04 Thread Luiz Capitulino
Yes, this also affects latest 2.6.27-rc kernels.

And Colin should be careful when applying his patch in current 2.6.27
because mainline now uses a mutex to protect some code regions.

This bug is also present in current Linus tree.

FYI, I have reverted the patch which is triggering the bug from Mandriva
kernel. Have a look at the Mandriva's ticket for more information.

Looks like it works if you pass 'noreplace-paravirt' in the command-line,
something like this:

boot: linux vga=0 noreplace-paravirt

Could someone please try it and report the results?

[Bug 246067] Re: Kernel panic during boot in VirtualBox with kernel 2.6.26.*-generic

2008-08-22 Thread Luiz Capitulino
Some news.

The original reporter of the Mandriva's bug has added a comment saying
that the problem also happens with QEMU. After investigating it for a
while I have found that, indeed, QEMU also OOPSes but with a different
behaivor. For example, QEMU works with latest 2.6.27-rc3, while
virtualbox does not and both get OOPSes with 2.6.26-rc1 and reverting
the DEBUG_RODATA commit makes no difference in QEMU, it still get
OOPSes.

But the important news is that I have reported this upstream and there
is a thread going on :)

[Bug 246067] Re: Kernel panic during boot in VirtualBox with kernel 2.6.26.*-generic

2008-08-19 Thread Luiz Capitulino
I can confirm that reverting commit
e587cadd8f47e202a30712e2906a65a0606d5865 (as pointed out in the upstream
bug report) fixes the problem for me, in Mandriva.

It is also important to say that I have ran git bisect between versions
2.6.25 and 2.6.26-rc1 (see comment #73) and it confirms that the commit
above is the culprit.

I will also revert that commit from latest 2.6.27-rc3 just to be sure
that it really fixes the problem.

Now the hard part: we have to investigate whether this is a kernel bug
(which, for some reason only happens on virtualbox) or whether it is a
virtualbox bug.

[Bug 246067] Re: Kernel panic during boot in VirtualBox with kernel 2.6.26.3-generic

2008-08-15 Thread Luiz Capitulino
I'm a Mandriva kernel team member and I would like to let you know that
we have the same bug in Mandriva.

Our bug report is at:

https://qa.mandriva.com/show_bug.cgi?id=42776

I could reproduce this problem with two (patched) Mandriva kernels
2.6.26.1 and 2.6.26.2. And also with an unpatched 2.6.27-rc2 kernel,
which is upstream.

The important information is that each kernel crashes in a different
site, which makes me think this is a virtualbox bug.

Now, some people have reported that it works with older kernels. I will
try to find a working kernel version and then try to locate the patch
(if any) which is triggering the bug.

Would be great if someone could try to downgrade his (or her) virtualbox
version to check whether it works with older versions.

I'm running virtualbox OSE 1.6.4 on Mandriva Cooker. My host kernel is a
(patched) 2.6.26.2.

I have found that kernel 2.6.25 works, while kernel 2.6.26-rc1 does not.

Please, refer to the Mandriva ticket for more information.
