Linux-2.4.19pre3-ac5

[Stephen Williams]

I can compile ac-5 fine but when trying to boot I get the following
error:

kernel BUG at ide-cd.c:790!
invalid operand: 0000

I am running 2.4.19pre3 without a problem.  I didn't have a way (as far
as I know) to get the full panic output but I can copy by hand and post
here if needed.

Have a good one,
Steve

It is a BUG() check to see if there are cases where the interrupt handler
is being set (re armed) while it is currently set for another event.

if (HWGROUP(drive)->handler != NULL)
     BUG();
ide_set_handler(drive, handler, timeout, expirey);

If we are reloading the handler but it was set but something else , never
called during a completion, and/or is dangling.  It is a typo my bad :-(

Edit and change it from "==" to "!="

Apology for the typo folks.

Now I'm confused. Should that be != to ==? :) And every instance I find?

It is a BUG() check to see if there are cases where the interrupt
handler
is being set (re armed) while it is currently set for another event.

if (HWGROUP(drive)->handler != NULL)
     BUG();
ide_set_handler(drive, handler, timeout, expirey);

If we are reloading the handler but it was set but something else ,
never
called during a completion, and/or is dangling.  It is a typo my bad :-(

Edit and change it from "==" to "!="
