I'm seeing this problem on two completely separate routers since I upgraded them to tomato v1.23. I configure tomato to store bandwidth monitoring stats on the JFFS2 partition. If I manually reboot the router, the JFFS2 partition DOES correctly mount. But, after a period of days (not exactly sure how long), the router seems to reboot (not sure how or why) and the JFFS2 partition is not auto mounted for some reason. I can mount it manually via the GUI and then the stats are then available, and new stats are logged. But stats in between are lost. I have not seen this bug until I upgraded both of these routers to 1.23. Is this a known issue?
