Same thing happens to me. kernel crashes, there is nothing in log files.
- What kind of power supply are you using and where it is attached to? Power connector or host USB.
true 3A, connected to power jack.
- do you have any additional hardware attached to USB?
NO. well yes, now I do, it's a KVM switch. but it doesn't matter if switch is in USB not. kernel crashes without that switch attached to USB. I actually attached KVM switch just to try to switch to cubietruck console in case if it stops responding over the network.
- have you installed system to NAND?
no, it boots a kernel from SD-card, then rest of it from SATA disk.
- have you modify anything else?
just copied system to SATA disk and installed some additional packages from Debian repositories. Not much actually – postfix, dovecot, apache, mysql, transmission, some old FIDO–net packages, vim, mc, some small libs and utils.
- what is the exact build and build date of Uboot.
last one from you repo.
- rather power cycle then reboot
been there done that. doesn't help.
What can I also add is that I had a setup using Igor's early images (about a year and a half old Wheezy, v1.8, with 3.4.79 kernel) and system uptime was almost a year. Now with latest images it stops every 4–5 days in best case, sometimes it runs for 1 or 2 days only.
