Kernel config (58.89 KB, application/octet-stream)

Description Kornel Lugosi 2009-12-03 21:27:08 UTC
I saw graphic corruption during boot process with kms but it was just a few lines. When I started the X server it got worse, I couldn't see anything, at one occasion it killed all my virtual terminals as well.
The error present without using kms, but not on the virtual terminal, only when I load X.

My configuration:
intel x3100
kernel: 2.6.32
intel driver: 2.9.1
xorg-server: 1.7.1

Sometimes the Xorg.0.log doesn't contain anything meaningful, but at one time it logged:
Fatal server error:
Failed to map batchbuffer: Input/output error

It usually (but not always) writes something to the console (which I forgot to write down, I'll reboot and tell, sorry).

It works flawlessly with 2.6.31.[0-6].

Attached my kernel config.

Can you bisect the failure?
Comment 3 Kornel Lugosi 2009-12-04 09:20:23 UTC
I'm going to try, but I can't promise that I'll have the time today.
Comment 4 Kornel Lugosi 2009-12-06 23:32:04 UTC
I'm sorry, but It seems like I won't have the time to debug this properly for a few more days.

Here's the Xorgs error message which is written to the console:
intel_bufmgr_gem.c:759: Error setting domain 604: Input/optput error

I also upgraded to xorg-server-1.7.3, but the bug is still present.

Anyone else managed to replicate this bug?
Comment 5 zhenyuw 2009-12-28 06:36:06 UTC
I bet dmesg will contain more info in case of failure.
Comment 6 Henry Gebhardt 2009-12-30 20:51:20 UTC
I guess I have the same bug starting with 2.6.32 and including 2.6.33-rc2 kernel. Thanks for looking into this. Some notes:

1.) I have 4GB of memory. Removing 2GB solves the problem, as suggested here:

2.) Using the "mem=3500M" kernel parameter solves it also, although I am left with only 3GB.

3.) The first bad commit is 176616814d700f19914d8509d9f65dec51a6ebf7, although the exact details of the problem have changed back and forth since then. For instance, sometimes the mouse can be moved, sometimes the screen stays black, sometimes the entire machine locks up s.t. shutting down via ACPI doesn't work any more, sometimes (but rarely) the above workarounds don't work, etc. This is the bisect message:

176616814d700f19914d8509d9f65dec51a6ebf7 is the first bad commit

    intel_agp: Use PCI DMA API correctly on chipsets new enough to have IOMMU
    When graphics dma remapping engine is active, we must fill
    gart table with dma address from dmar engine, as now graphics
    device access to graphics memory must go through dma remapping
    table to get real physical address.

4.) When it does not work, dmesg reports the following in syslog (2.6.33-rc2):

Comment 7 Kornel Lugosi 2009-12-30 21:33:02 UTC
I'm glad that someone can reproduce my problem.

I can't remember anything like that from dmesg, but I'll build a kernel without 176616814d700f19914d8509d9f65dec51a6ebf7 and see what happens.
Comment 8 Henry Gebhardt 2009-12-31 00:26:15 UTC
One more thing I just tested. Disabling CONFIG_DMAR also solves the problem, but disabling CONFIG_DMAR_DEFAULT_ON is not sufficient with a 2.6.33-rc2 kernel. Thanks, H.

This is dup of bug 14627, I have attached a patch there.
Comment 10 zhenyuw 2009-12-31 04:48:39 UTC
please help to test the new patch on bug 14627. thanks.
