I just ran into the problem Yang described, using jemplode 47 to add "[startup]
ReserveCache=64"
to config.ini. I'm not running anything other than Hijack and the default player software.

After doing the fsck's manually via the serial port, rebooting, and watching the unit rebuild both databases, now emplode tells me Error 0x00041002.

(I mention this only because it does seem there is something wacky with using jemplode to edit config.ini.)
