Actually, I did read that from the Changes file. But it sounded so
overwhelmingly x86 that it never occured to me to try it for Alpha. Here
is the text:

...

   <CTRL><ALT><DEL> now performs a cold reboot instead of a warm reboot
for increased hardware compatibility. If you want a warm reboot and
know it works on your hardware, add a "reboot=warm" command line option
in LILO. A small number of machines need "reboot=bios" to reboot via
the BIOS.

...

The mention of LILO and BIOS led me to instantly dismiss it as a change
which didn't apply to me. I'll give it a try with SRM tonight and see what
happens.

Another point that someone on this list brought up was glibc-2.1. IIRC the
possibility was mentioned that breaking the reboot(2) syscall in glibc
might have prevented init from telling the kernel to inform of of
ctr-alt-del and let it do the work.

thanks,
