Roughly the fixes are:

1. fix shutdown (esp. if GEM=ROM) - see

http://sparemint.org/bugtracker/view.php?id=162

2. allow a tty to be opened for non-blocking IO. This is just a few days  
old and has not been well tested nor discussed.

3. enable gcc2-compilation.

4. improved load-calculation: use time not spent in kernel to get load  
instead of counting running processes every 5 seconds. But this  
contradicts to the docs in

http://info2html.sourceforge.net/cgi-bin/info2html-demo/info2html?(libc.info.gz)Processor%2520Resources

"
 processors are not already overused.  Unix systems calculate something
 called the "load average".  This is a number indicating how many
 processes were running.  This number is average over different periods
 of times (normally 1, 5, and 15 minutes).
"

Obviously the new method is more exact e.g. the original did not see any  
process that starts and terminates between two samples.

Also there's a lot of debug-code because I encountered some timing-issues  
on aranym that may affect the load-calculation and other things.

5.  Add some stack-checking code to find the bug that caused  
pixel-detection to fail (obsolete IMHO).

6. because sys_b_bioskeys is not reentrant, don't permit it to be entered  
again using kbd_lock-semaphore. There's still the possibility that the  
process that called sys_b_bioskeys crashes during execution of  
sys_b_bioskeys, and kbd_lock is never reset, so one can only reboot.

7. Alans patch to fix the key-repeat on aranym.



If no one that uses my kernel sees no problems with the shutdown (1.) I  
will commit that. Any other on demand.



Did you find a solution for the renaming loaded files on FAT?


I guess I have to start another thread for my pending XaAES-changes.
