This MIGHT have something to do with my problem, actually. I've been having spontaneous reboots for about a month now. I proceeded to install syslogd and logged a bunch of messages that way for a while, but I never saw anything that was exactly the same regularly - just that something would die, and then most of the time, watchdog would flip out and reboot because that process died. It seems to always have to do with some sort text selection/copying/pasting, or new data coming in to my N900 (typically lots of stuff coming in from the internet). I am pretty sure I remember some error about a device not being found in the syslog logs as well...

At the same time, I have had the /opt (/home/opt technically) partition occasionally become "read only", and I believe ONCE I had /home/user/MyDocs become read-only as well... Anyway, I don't have anything to easily diagnose when swapping happens, but when the N900 does this, it's in situations I would think it likely to be swapping...

Were you ever able to fix your N900 in a more 'true' way, like find some way to fix your eMMC chip more solidly to its casing? Or did/do you just use it without swap / with swap on an SD card?
