I just wish the information at l-o-l was organized for a search on
something other than brand, since brand is sometimes that target rather
than the key, in very general terms.

I was looking for a laptop which had Centrino/pentium-M for battery life
and which worked with 2.6 kernels. Spent a lot of time and either there
isn't one or someone with more time than I will have to find it.

Given the state of 2.6 power management, I have no trouble finding units
which won't boot, or suspend, or have disfunctional parts, but I haven't
identified the one which actually works :-(

I'll go look at the other links, but I think they are optimized for
search by brand as well.

Possble Toshiba 3010CT IDE port from NetBSD?

Hi, 
In my quest for a DMA driver for the IDE controller in my Toshiba
3010CT, I've come across a code chunk in netBSD for it (see end of
message).
It (to my untrained eye) scans the PnP device listing for "TOS 7300" and
then does some (apparently minor) tweaks to get it to work. Compiling
2.6.0-rc8 and doing lspnp shows this to be present on my laptop. Looking
at /drivers/ide/ide-pnp, one can add a PnP device string in to get it to
recognise other IDE controllers.
So, I added "TOS 7300" in there and it the toshiba PnP controller gets
recognised now. 
But, still no DMA. I know there's a few things to set in the hwid (?)
structure, but my feeble attempts to do so result in kernel panics upon
ide init :-)
What bugs me is this looks to be in the "trivial" department... but I
have no clue, and a slow laptop to compile/crash/compile/crash with.
Anyone able to port this properly? 
Alternatively , anyone got any suggestions on how to do this? 
I know, 3010CT's are *old* now, but still I'd like to get it to go. 
Regards 
David

Resume after suspend


Hi!

I'm using the kernel 2.6test8 from kernel.org with apm on my Laptop.
If I have X started I can't resume when suspend is finished. It's working 
without X. 
Is there any problem with the kernel, apm and X? 
Here some informations about my system:

Hardware:
Gericom Webgine XL Force
P4 <at> 2,4GHz
512 MB of RAM
nVidia GeForce 4 Go (32 MB memory)
BIOS supports APM and ACPI

Software:
Gentoo Linux
Kernel 2.6test8 from kernel.org
apmd-3.0.2-r3

Suspend with ACPI is with "echo 3 > /proc/acpi/sleep" working but I can't 
resume. Here it is the same with and without X.
I tried to get help in several other Mailinglists but the problem isn't solved 
yet.

Is here anyone who can help me?

Thanks
Olli

APM suspend on 2.6.0-test9 causes Toshiba 470CDT laptop to hang after resume

When I suspend and later resume on this laptop it looks like 
everything that involves the disk breaks.  For example, when I 
tried this after resume:

dmesg > dmesg.log
sync

it hung on sync. The kernel seems to continue working, for 
example I can scroll up, but anything I try to run hangs. USB 
seems to break as well, if I connect a card reader after resume 
there's no kernel messages, and its LED doesn't light. Here are 
some messages I copied:

(apm --suspend)
hdc: start_power_step(step: 0)
hdc: completing PM request, suspend
hda: start_power_step(step: 0)
hda: start_power_step(step: 1)
hda: complete_power_step(step: 1, stat: 50, err: 0)
hda: completing PM request, suspend
ohci_hdc 000:00:0b.0: suspend D4 --> D3
ohci_hdc 000:00:0b.0: suspend to 3
ohci_hdc 000:00:0b.0: suspended

(resume, apm --suspend not returning, Ctrl+C works to abort it)
ohci_hdc 000:00:0b.0: resume from state D4
ohci_hdc 000:00:0b.0: OHCI 1.0, with legacy support registers
ohci_hdc 000:00:0b.0: control 0x000 HCFS=reset CBSR=0
