We should now decide which modules to add in zaurus.inc (i.e. MACHINE_EXTRA_RRECOMMENDS = kernel-modules for *all* compiled modules or a list).

I can confirm that touchscreen 'works' again on corgi(C860) and poodle. Well, I cannot. My OE image is broken again. That is why I copied my old good 2.6.26RP image to the new OE image (plus odev-compat stuff), and I was surprised - touchscreen does not work there as well. So it is definitely issue outside kernel. Just some issues to cure: - poodle(kdrive-fbdev): at gpe login touchscreen calibration is requested, crosshairs are plotted, after calibration no input from keyboard/virtual kerboard :/ - c7x0(kdrive-imageon): pointercal defaults are used (and those are slightly wroing on my 2 corgi C860). Gpe login is ok, keyboard working. Though, if you try to recalibrate from within gpe the crosshairs are not drawed so calibration is impossible Yes, I seen this bug in Xfbdev pointercal as well on SL-C3200. But Xorg calibration now works (well, the application works, but short tap paints a pretty long line, so the result of calibration is still unusable). I am now trying to locate the regression (or race condition?). Is the current OE still using module autoload? Or was this moved to udev and platform device tables? I the latter case the fix should be done in the kernel. Ah, this is nice question: we newly came on open air after years with 2.6.2x and now we'll discover new bugs;) FWIW in OE there is a mix of modules management: some are in kernel.bbclass, others in linux.inc and finally in machine.conf. I'm still trying to understand what's happening using latest udev. Well, again - snd-soc-spitz-not-autoloaded is a regression outside kernel.

I got WLAN working, Bluetooth works, even tslib started to work again for unknown reason, Xfbdev works, Xorg works (but it is unusable due to very noisy ADS7846 driver and broken xf86-driver-input-tslib). Regarding the defconfig and spitz embedded hardware, the driver for ICL7106A and PXA RTC were missing or not loaded. I don't know about sound (I found the fix sent to the list with my kernel). I have maintained my experimental configs separately since 2.6.26-RP. It diverged a lot. I am not sure about effect of many generic kernel settings. Which one is better and which one is worse... I'll compare your one and my one. For example, yesterday I have found an option, that considers SD card removal/insertion during suspend (MMC_UNSAFE_RESUME). It would be nice to have this option disabled. But it makes impossible to suspend when booting from SD. (Work-around: While booting from SD, bootloader have to pass proper removable value to the kernel MMC driver (I did not test it yet). please post/commit the shrinked defconfig (make savedefconfig): I'm trying to keep all the Zaurus in sync and that's much easier to diff. Thanks for the hint. FWIW USB-host is only for spitz/akita/tosa, though. Yes, it is. But USB host is very important for many users (like me). Your config lacks many useful external USB devices support: - USB HCI - required for any generic USB Bluetooth dongle. - More WLAN drivers (my WLAN dongle is RT3070 and it is one of few dongles, that is able to live with 150mA. People using external power or power hack may need other WLAN USB drivers). - USB to serial adapters are needed not only for serial cables, but also for many other devices (GPS, Arduino,...). - I don't have any Ethernet adapters, but people have. - Guessing whether somebody needs more obscure drivers like special USB keyboards, SDIO GPS. Regarding the missing sound: This is just an easy bug in the kernel platform tables - udev does not know that it should load snd-soc-spitz. Loading it manually works-around the problem. Pls check machine/include/zaurus.inc Are you sure we have the right modules configuration (btw it's a mess in OE)? I just copied the lines from linux-rp.inc... Yes, it seems that we have right modules. Just snd-soc-spitz is not autoloaded after the boot (it happened with 2.6.26-RP). I see loaded snd-soc-pxa2xx-i2s (required for the I2S bus) and snd-soc-wm8750 (codec driver), but not snd-soc-spitz (it defines Spitz sound routing and controls additional mute transistors). Is the current OE still using module autoload? Or was this moved to udev and platform device tables?
