I've Cc'd some powerpc folks because via_pmu_interrupt is in the Macintosh PMU driver. Hmm, I just looked back in my logs and I also got that message with commit 7a883eaf62f4b943ebec738ce3b0796c67ef5d32. Before that I used 6c8dca5d53f95009d4fff00195bf38f277dc4366 and there was no badness message logged by that one. There's only about 480 commits between those two, so I can bisect it if necessary. The call traces differ, so here are both messages. v2.6.23-rc2: ------------[ cut here ]------------ Badness at kernel/irq/resend.c:70 NIP: c0054ca4 LR: c0054c78 CTR: c00162b0 REGS: c0473d80 TRAP: 0700 Not tainted (2.6.23-rc2-g036acf4f) MSR: 00021032 CR: 42000024 XER: 00000000 TASK = c04451e0[0] 'swapper' THREAD: c0472000 GPR00: 00000001 c0473e30 c04451e0 00000178 0000002f 00600000 c0480000 0000002f GPR08: 000186a0 c0480000 0048002f 00000400 00000000 00000000 00000000 00000000 GPR16: 00000000 00000000 00000000 00000000 00000000 40900000 00d3bbc0 00000000 GPR24: c0444000 c0480000 c0480000 c043b81c 00000001 0000002f 00024408 c044b1bc NIP [c0054ca4] check_irq_resend+0x5c/0xc0 LR [c0054c78] check_irq_resend+0x30/0xc0 Call Trace: [c0473e30] [c0054c78] check_irq_resend+0x30/0xc0 (unreliable) [c0473e50] [c00547d0] enable_irq+0x84/0xa8 [c0473e60] [c0220fec] via_pmu_interrupt+0x3d8/0xac0 [c0473e90] [c0053dfc] handle_IRQ_event+0x4c/0xa0 [c0473eb0] [c0055250] handle_fasteoi_irq+0xac/0x100 [c0473ec0] [c0006528] do_IRQ+0x68/0xa8 [c0473ed0] [c000ffe8] ret_from_except+0x0/0x14 --- Exception: 501 at cpu_idle+0x88/0xd0 LR = cpu_idle+0x88/0xd0 [c0473f90] [c00090bc] cpu_idle+0xcc/0xd0 (unreliable) [c0473fa0] [c0351f9c] rest_init+0x58/0x68 [c0473fb0] [c04189a0] start_kernel+0x260/0x274 [c0473ff0] [00003860] 0x3860 Instruction dump: 4e800421 801f0000 3d20c005 57cb052a 39295030 2f0b0400 7f804800 419e0030 3d20c048 800994e4 7c000034 5400d97e <0f000000> 2f800000 41be0048 38000001 7a883eaf62f4b943ebec738ce3b0796c67ef5d32: ------------[ cut here ]------------ Badness at kernel/irq/resend.c:70 NIP: c0054bfc LR: c0054bd0 CTR: c00162b0 REGS: effc3e60 TRAP: 0700 Not tainted (2.6.23-rc1-g6cc0258f) MSR: 00021032 CR: 48000084 XER: 20000000 TASK = effc17f0[1] 'swapper' THREAD: effc2000 GPR00: 00000001 effc3f10 effc17f0 00000178 0000002f 00000000 c0470000 0000002f GPR08: 000186a0 c0470000 0048002f 00000000 82000022 00000000 00000000 00000000 GPR16: 00000000 00000000 00000000 00000000 00000000 40900000 00d3ad48 00000000 GPR24: c0443000 c0470000 effc2000 c043ef4c 00000001 0000002f 00024008 c044a1bc NIP [c0054bfc] check_irq_resend+0x5c/0xc0 LR [c0054bd0] check_irq_resend+0x30/0xc0 Call Trace: [effc3f10] [c0054bd0] check_irq_resend+0x30/0xc0 (unreliable) [effc3f30] [c0054728] enable_irq+0x84/0xa8 [effc3f40] [c0220e74] via_pmu_interrupt+0x3d8/0xac0 [effc3f70] [c0430f28] via_pmu_start+0x168/0x190 [effc3f80] [c04171e4] kernel_init+0xc8/0x284 [effc3ff0] [c0010800] kernel_thread+0x44/0x60 Instruction dump: 4e800421 801f0000 3d20c005 57cb052a 39294f88 2f0b0400 7f804800 419e0030 3d20c047 800974e4 7c000034 5400d97e <0f000000> 2f800000 41be0048 38000001 -- Paul Collins Wellington, New Zealand Dag vijandelijk luchtschip de huismeester is dood - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
