Public bug reported:
Binary package hint: acpi-support
I have an Everex StepNote 2053 T laptop (see below **) that doesn't
resume after a suspend in Ubuntu 8.10 Intrepid; worked fine in Hardy.
More details: I recently updated from Hardy to Intrepid, using the
Update functionality of the GUI-based package manager. I've since
updated to the latest package releases, and am running the
2.6.27-9-generic kernel at the moment (will attach more detailed system
info). I have the SDHCI and SDHCI-PCI modules blacklisted (see Bug
#187671), but other than that it's a fairly standard Intrepid install.
I'm apparently running version 0.114 of the acpi-support package.
When I boot into this kernel, the earlier 2.6.27-7-generic kernel, or a
2.6.27.7 kernel I compiled form kernel.org source, and I suspend the
laptop from the System / Shut Down menu item in Gnome, the laptop fails
to resume. Booting into an old 2.6.26 kernel I compiled myself from
kernel.org source, suspend/resume works. It also used to work fine in
Hardy using kernels supplied by Ubuntu (which were conveniently erased
when I upgraded to Intrepid) when I was still running Hardy.
What I'm seeing with the current kernels, after I suspend and then hit the
space bar to try to resume, is a blinking cursor in the upper-left of the
otherwise black laptop screen. In fact, before I added this line to my startup
sequence
echo 3 > /proc/sys/kernel/acpi_video_flags
I couldn't even see the cursor -- the screen was just black (I added this line
to startup because a friend with a different laptop was seeing a black screen
and this fixed his problem, but it didn't fix my problem, just made the cursor
visible). The fan and drives start up and make noise, but the laptop isn't
usable.
I've tried control-alt-f1 (and other f-keys) and control-alt-backspace,
but they have no effect.
I will attach lspci output and some other system output, and do some
more debugging (I found debugging guides
https://wiki.ubuntu.com/DebuggingKernelSuspend and
http://ubuntuforums.org/showthread.php?p=3066404)... will report these
in separate comments, coming shortly, but I wanted to get the bug
reported first.
