I just noticed that 2.1.90 (my first SMP kernel with SMP board) -> 2.1.93 give:
Apr 7 20:43:55 moving kernel: Linux version 2.1.93 (root@moving) (gcc version 2.8.1) #3 SMP Tue Apr 7 19:19:11 EDT 1998 Apr 7 20:43:55 moving kernel: Unknown interrupt Apr 7 21:16:13 moving kernel: Intel MultiProcessor Specification v1.1 Apr 7 21:16:13 moving kernel: Virtual Wire compatibility mode.
Doesn't look harmful but probably shouldn't be there...
Full 2.1.93 listing on a Tyan Tomcat IVD with two Pentium 133's:

Too bad it doesn't say which interrupt number it received. (And I don't do asm well enough to try.)
