I followed up on the D state, and found that it usually indicates a kernel or device driver problem. Based on that, and the facts that I had to shutdown several times by pulling the battery out, and that the way I installed Debian wasn't completely vanilla (I tried to install into an existing partition), I decided that it would probably be a good idea to reinstall from scratch, and I've now done that. What does vmstat say (I usually run vmstat 2)? What are your top memory-consuming processes (in terms of both real and virtual memory footprint)? I'm afraid I didn't check these before reinstalling. Do you have a swap partition (or file)? Are you running from the internal NAND flash, or a micro-SD card? I was running from the first partition of a micro-SD card. No swap partition, but post-installation I had prepared a 200Mb swap file on /dev/mmcblk0p2. I hadn't added a mount and swapon for this to /etc/rc.local, so it wasn't being used during the boot. I did the mount and swapon later - I think after I'd already tried starting Emacs, and that had hung - and it didn't appear to make any difference (apart from top reporting the available swap). - Battery not apparently charging.

There's mention of issues with APM on the DebianOnFreeRunner Debian Wiki page: http://wiki.debian.org/DebianOnFreeRunner#KnownProblems That looks like a red herring / misunderstanding to me. IIUC, it was resolved some months ago by an apm-emulation script that calls the dbus API. Post-reinstall, openmoko-panel-plugin is showing a believable battery status, and responds to plugging in the USB cable, and I'm pretty sure that it did that for a while after my first install too. So I guess I must have broken it by one of my first install experiments. - ssh (via USB) not working. The desktop end looks fine: Similar situation here. Post-reinstall, working fine. So, right now I've reinstalled from scratch, with QI=true SD_SWAP_SIZE=512 TASKS= ./install.sh all My problem now is no GSM - which was also the case after my previous install - with the symptoms being that - Zhone briefly says Usage: Requested resource GSM with error (or a permutation of those words) - Zhone's phone, messages and contacts buttons stay greyed out. I've rebooted twice since reinstallation, so it isn't a first-boot problem. GSM works fine on OM2009/Paroli (in NAND), so it isn't a SIM-seating problem. I don't have a PIN, so it isn't a PIN entry problem. Any ideas?

[debian] unexpected troubles
Hi there... Is this generally the best place for Debian questions? Or is smartphones-userland better? I've just installed Debian again, and am surprised to be experiencing some low-level problems. Hopefully they are easily fixable. As context, what I'm aiming at is: - Debian - for the best available package management - E17 + Illume - for Raster's keyboard, decent launcher and easy switching between windows - John Sullivan's fso-el - for performing phone functions from within Emacs. I've installed e17, and the UI comes up as expected. I set an overall scaling factor of 2, to make everything easier to read and press. The problems I'm seeing now are: - Load average unreasonably high. Right now, for example, my top says load average: 8.11, 8.13, 8.09. Yet CPU usage is only reaching around 6%. - Emacs never appears, yet can't be killed. E.g. I clicked on the launcher icon for Emacs about an hour ago, and nothing has appeared yet. ps waux shows that there is an emacs process: root 1579 0.0 3.2 25700 3952 ? DNs 17:44 0:00 /usr/bin/emacs23 But kill 1579 and kill -9 1579 seem to have no effect on this. - Battery not apparently charging. I'm using the USB lead from another Linux computer, which successfully charges OM2009/Paroli and SHR. But with Debian there is no + on the battery icon, and no orange (or blue) light behind the power button. - ssh (via USB) not working.

I get a message saying that the system is going down, but then nothing else happens. Can anyone see the cause(s) of these problems and suggest how to fix them?
