Tinycore 4.1 won't reboot my Acer Aspire One netbook (the original, model ZG5). To isolate the issue, I choose "Exit to Prompt" from the menu in my flwm session to get right down to the console. There I type the command "sudo ./sbin/reboot". The TC scripts do all their work, and the line "Requesting system restart" appears on the console. Then the screen goes black, but the system doesn't restart.
By contrast, the shutdown command works fine. And Ubuntu can make the machine restart.
This is not a completely clean TC install: I upgraded from version 3.x by replacing just the kernel and initrd (from the distribution-files section of the downloads page), then running the application updater. The apps-audit now says my system is fully up-to-date.
I expect this problem might originate outside TC, but hope for yet one more example of smart TC people solving problems of a general nature. Any ideas? Thanks!
