[Fixed] SATA/AHCI related crash

[mhanor]

This is not a regression (see bug 13105), but I think you could squash this bug before the final release of VirtualBox 5.0
It's very easy to reproduce on a Linux host. I can reproduce the crash on my Ubuntu 14.04 x64 host, using VirtualBox 5.0 Beta 4, a live Lubuntu 14.04.1 x86 VM and a mapped device. Just run the commands below, in a terminal. You'll need to logout after adding the user account to the disk group.

Code: Select all

sudo usermod -a -G disk $USER
sudo dmsetup create bad_disk <<EOF
0 100000 zero
100000 1 error
100001 100000 zero
EOF
VBoxManage internalcommands createrawvmdk -filename bad_disk.vmdk -rawdisk /dev/mapper/bad_disk

Then create a Ubuntu x86 VM, add the bad_disk.vmdk to the SATA controller and mount the Lubuntu 14.04.1 ISO image, boot the live image, and run at the guest terminal:

Code: Select all

sudo cat /dev/sda > /dev/null

Just to let you know, we are able to reproduce this problem, thanks for the nice test case. We are working on a fix but most likely it will not be ready for 5.0.

Actually in the meantime there is a fix available (after RC2) and I would like to provide you a test build. Which package do you prefer?

[mhanor]

A Linux 64 bit package (I'm using Ubuntu 14.04 x64).

[frank]

Sorry for the late response. Here is a 64-bit Linux .run package. And here is a 64-bit Ubuntu .deb package.

[mhanor]

I can't reproduce the crash using the above test case and the new build.

Thanks for testing! As always you are a big help!
