What kernel version are you using? A problem similar to this was fixed in 22.214.171.124-73.
Also, if using at least that kernel and this still happens, how do you go if you also boot with VT-d disabled in your bios (or intel_iommu=off on kernel commandline)?
Kernel 126.96.36.199-112.fc13.x86_64, will try mentioned options.
intel_iommu=off do not work for me.
Okay. Well my only real suspect (older kernel without the fix) is ruled out.
Could you boot with "log_buf_len=1M drm.debug=14" appended to your kernel options and get me a new dmesg log please?
Also, if you can access it over ssh it'd be great if you could:
- boot with "nomodeset 3"
- echo mem > /sys/power/state
- ./vbtracetool -lp 2>post.iolog
- ./vbtracetool -w 2>vbios.rom
- mail post.iolog and vbios.rom to me
You can get vbtracetool from http://cgit.freedesktop.org/~stuart/vbtracetool, you'll need pciutils-devel installed to build it.
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '13'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 13's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 13 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
