Thanks for the follow up.
No, we shouldn't close this --- it seems it's just another sign that
xhci support is a little broken in squeeze. Nice to see that's the
*only* problem here. :)
What is the latest squeeze kernel you've tried and reproduced this
with? ("cat /proc/version" will say the current version in
parentheses.)
To move forward:
- Please attach "acpidump" output. (I doubt it's relevant, but it's
useful to have for reference.)
- Please test a v3.2 release candidate from experimental. The only
packages from outside squeeze that should be needed for this, aside
from the kernel image itself, are linux-base and initramfs-tools.
- If it reproduces the problem, please blacklist the xhci_hcd
module by writing
blacklist xhci_hcd
to a file /etc/modprobe.d/mm-blacklist-xhci.conf, run
update-initramfs -u -k all
and reboot to try again without USB 3.0 support. If we're very
lucky, this will work around the problem. In that case, please
write a summary of the problem to upstream
(linux-...@vger.kernel.org, cc-ing Sarah Sharp
<sarah.a.sh...@linux.intel.com> and either me or this bug log so we
can track the resulting discussion). Be sure to include:
- steps to reproduce the problem
- symptoms, and how they differ from what you expected
- ways to avoid triggering the problem (maybe some USB ports
trigger it and others don't? etc)
- full "dmesg" output from booting, and a photo of the screen
after reproducing the problem (ideally by running "modprobe
xhci_hcd" in the very same run of Linux), as attachments
- which kernel versions you've tested, and what happened with each
- a link to this bug log for the full story
- any other weird symptoms or observations
Thanks for your patience and hope that helps,
Jonathan
