Bug ID: 104271
Summary: Boot crashes on Lenovo W520 KVM and Discrete Graphic
enabled in BIOS
Product: Virtualization
Version: unspecified
Kernel Version: 4.1.6
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: blocking
Priority: P1
Component: kvm
Assignee: virtualization_kvm@kernel-bugs.osdl.org
Reporter: streibel.2003@gmx.net
Regression: No
Booting stops/crashes on a Lenovo W520 Notebook with these BIOS Settings:
- Virtualization
Intel Virtualization Technology: Enabled
Intel VT-d Feature: Enabled
- Display
Boot Display Device: ThinkPad LCD
Graphics Device: Discrete Graphics
OS Detection for NVIDIA Optimus: Disabled
Booting starts and the last lines show that the kernel cannot access the hard
disks (lines starting with ata2 and ata1). The last lines are:
[ TIME ] Timed out waiting for device dev-disk-by\x2duuid-c30...4394b6b.device.
[ DEPEND ] Dependency failed for
/dev/disk/by-uuid/c305bd9f-9d6...7-359b94394b6b.
[ DEPEND ] Dependency failed for Swap.
After that booting stops.
Additional Information:
- This is no hardware fault. The error can be reproduced on a different W520.
- Booting also crashes with these kernels:
- 3.16.0 (kernel from Debian Jessie)
- 4.1.0 (backported kernel to Debian Jessie)
- Booting succeeds if:
- both virtualization flags are set to Disabled in the BIOS
or
- Graphics Device is set to "Optimus" in the BIOS

Does it work well on windows? I guess it's a BIOS problem. finding a avaliable
disk device is the job of BIOS, and the problem just right occurs when you
change the BIOS settings.

Yes, it works on Windows 7. I did not recognize any problems there.
Ok, I did not try any virtualization like Virtual Box under Windows,
but everything else seems to work.
Even if it is a BIOS problem, then Windows obviously found a way to handle it.

You might get more attention moving this bug to Drivers/PCI and including the
full dmesg or console log of the failure and lspci -vvv so we know something
about your system. If it doesn't boot, there are always screen shots or
netconsole if you're serial port challenged.
KVM is a hypervisor, it has nothing to do with your system not booting. More
likely it's something with the IOMMU. Does disabling VT-d help? What about
booting with iommu=pt? BTW, reproducing on another W520 doesn't mean the
hardware isn't broken, it just means this isn't a point defect. Hardware is
broken a disturbing amount of the time.

Ok, will move it to Drivers/PCI.
Output of lspci -vvv now is in the appendix.
Output of dmesg is not included because that only shows output of a
successfully booted kernel. I even installed bootlogd but its log file does not
show error messages.
I made some pictures with my camera but I do not dare to attach those somewhat
big jpg files here. But if you really need them I can attach them.
The trouble starts (most of the time) right behind the line:
shpchp: Standard Hot Plug PCI Controller Driver Version: 0.4
Yes, disabling VT-d did help. Booting succeeded again.
Using "iommu=pt" however did not help. Same symptoms.
BTW, I wanted to express that my special notebook is not broken.
Not more broken that all (many/most) of the others W520s around.

As Alex suggested I moved this bug to Drivers/PCI to get more attention.
However now I have the impression that this bug does not get any attention at
all any more.
Did I miss any necessary action beside moving this to Drivers/PCI?
