I am by no means a Linux guru, but after reflashing my device and getting more random reboots than usual, I started looking at what might be the problem. Is it good practice to set up a new swap file on your memory card or to use the old one? Does this matter? It seems like it might matter but I don't know. I turned off the swap file for now and will see how things go. Please let me know your expert opinions on this matter. Thanks.

BTW, I have 2007he, the version before MicroB as well as seatbelt set to 60 and the wlan bugfix installed.

I never had a random reboot in the 6 months that I own my N800 (and I use it a lot). A first thing I would try is to disable swap file and see if it fixes the problem with random reboots.

NOT having swap enabled increases the risk of a kernel crash ("random reboot") - even more so on the 770, as it is twice as fast at running out of memory to a degree where some critical process cannot allocate memory any more.

The contents of the kernel file are irrelevant - there is no need to clear or rebuild it, ever, as any page copied over from memory will by the very principle of paged memory overwrite whatever that segment of the swap space may have previously contained.
