With this patch, my Powermac (ppc32) spews 711 (I think)
warning messages during bootup. The first one looks like:
Calibrating delay loop... 1064.96 BogoMIPS
Mount-cache hash table entries: 512 (order: 0, 4096 bytes)
Badness in schedule at kernel/sched.c:2153
Call trace:

[c0006bac] check_bug_trap+0x84/0xac
[c0006d38] ProgramCheckException+0x164/0x1a4
[c0006240] ret_from_except_full+0x0/0x4c

[00000000] 0x0
[c02ce5a0] start_kernel+0x158/0x184
[000035fc] 0x35fc
and this goes on until:
Badness in schedule at kernel/sched.c:2153
Call trace:

[c0009128] kernel_thread+0x44/0x60
adb devices: [2]: 2 2 [3]: 3 1
ADB keyboard at 2, handler set to 3
The full dmesg is 322K, and is up at:
http://www.rivenstone.net/linux/samarkand.dmesg
Most of the traces look something like the bottom one.
