Installed deblet on an N810, Using External slot 8 gig Micro (with mini converter) card.
512 megs fat32 partition Primary (mmcblk1p1) - So Maemo doesn't whinge.
(remainder) Linux Partition (Ext2) Primary (mmcblk1p2).
512 linux swap partition. Primary (Although I think it should be Logical right?) (mmcblk1p3).

Same problems as above.. Selecting 'Deblet on external'* menu apon boot. Screen goes black and then reboots.

Mounting the partition in maemo and cat'ing /var/log/ boot log file from the External card shows it's empty..

*sigh* I've had Deblet working a release or 2 ago on this same Nokia N810..

Anyone have any ideas? Or could describe as requested above a simplistic Howto?
