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: [c00099e4] dump_stack+0x18/0x28 [c0006bac] check_bug_trap+0x84/0xac [c0006d38] ProgramCheckException+0x164/0x1a4 [c0006240] ret_from_except_full+0x0/0x4c [c02021bc] schedule+0x24/0x684 [c0005e80] syscall_exit_work+0x108/0x10c [c02e0ad0] proc_root_init+0x14c/0x158 [00000000] 0x0 [c02ce5a0] start_kernel+0x158/0x184 [000035fc] 0x35fc
and this goes on until:
Badness in schedule at kernel/sched.c:2153 Call trace: [c00099e4] dump_stack+0x18/0x28 [c0006bac] check_bug_trap+0x84/0xac [c0006d38] ProgramCheckException+0x164/0x1a4 [c0006240] ret_from_except_full+0x0/0x4c [c02021bc] schedule+0x24/0x684 [c00062ec] resume_kernel+0x38/0x58 [c020249c] schedule+0x304/0x684 [c002c85c] worker_thread+0x258/0x27c [c00317d0] kthread+0xb8/0xc0 [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.
