I've pushed the camera fix, bluetooth and mmc patches below & I've
updated the remaining hacks on my website.

Attached are some patches to boot N810 with current linux-omap kernel and
mount root on the internal MMC. I'm currently booting to Debian sid
created with debootstrap, but this should work for any distro.
I also put up a page for it with more notes:
http://www.muru.com/linux/n8x0/
Only the first few patches are ready for merging, hopefully we can get
all the attached hacks worked away soon..

What would you recommend? Do you have it in RD mode with no-lifeguard-reboots (check flasher options)? If it's a reboot performed by the sw watchdog because some component is crashing too many times, you could get a bit further in the boot sequence, maybe to the point of ssh into the tablet. -- Cheers, Igor --- Igor Stoppa Next Generation Software Nokia Devices R&D - Helsinki -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
