Different symptoms than described
in this thread.We're playing around with custom kernels to do hings with loopback filesystems (mainly mods to loop.c and loop.h) so that we can store user data (bookmarks, mail account config, and the like) on a loopback.
The loopback is mounted to /home.
Mounted the loopback, started a few other programs, started the mail program, and the Z gave a low memory warning.
Then it died screaming. Screens rotating, error messages, so we rebooted. It shut down, but wouldn't reboot. Hangs at the Sharp screen. B+D boot hangs. Reflashing the kernel (option 4 in the maintenance menu) hangs. Any other option in the maintenance menu just boots it, then it hangs. EX: Normally, when restoring to factory state, you do option 3, then option 1. On this Z you hit option 3 and it boots.
