Here's one feature which didn't get in before the freeze: morse code kernel
panics, recently updated to 2.5
Szepe. With this patch, a 2.5 kernel which goes into a panic state
will blink out the panic message in morse code using the keyboard LEDs.
Possible future enhancements include audio output using the PC speaker or a
sound card. One developer has mentioned the
of having a nearby machine with a microphone to detect and
decode the encoded panic message.
One might well be tempted to object that the number of people clamoring for
this feature has been relatively small. But there is actually a serious
side to this patch. It is well known that production Linux systems never
panic, but if, someday, a box were to be struck by a cosmic ray and go
down, its owner might like to know about it. Preferably before the "where
has your site been this last week?" mail starts to show up. The morse code
patch could, with a bit of work, be the beginning of a more general panic
notification feature. It could be useful, even if you hope you never
actually make use of it.
