Hello everyone, occasionally the TWL4030 driver on the 3430SDP freaks out on boot. (This is either an ES2.0 or ES2.1, not sure.) Here's a partial console log with initcall debugging enabled. This probably happens every thirty or forty boots, I would guess. The board does boot to userspace when this happens. Perhaps the TWL4030 experts out there might know what's going on? - Paul calling i2c_init+0x0/0x60() initcall i2c_init+0x0/0x60() returned 0 after 7 msecs calling omap_i2c_init_driver+0x0/0x1c() <6>i2c_omap i2c_omap.1: bus 1 rev3.12 at 2600 kHz <6>i2c_omap i2c_omap.2: bus 2 rev3.12 at 400 kHz <6>i2c_omap i2c_omap.3: bus 3 rev3.12 at 400 kHz initcall omap_i2c_init_driver+0x0/0x1c() returned 0 after 22 msecs calling twl4030_init+0x0/0x20() <6>TWL4030: TRY attach Slave TWL4030-ID0 on Adapter OMAP I2C adapter [1] <6>TWL4030: TRY attach Slave TWL4030-ID1 on Adapter OMAP I2C adapter [1] <6>TWL4030: TRY attach Slave TWL4030-ID2 on Adapter OMAP I2C adapter [1] <6>TWL4030: TRY attach Slave TWL4030-ID3 on Adapter OMAP I2C adapter [1] initcall twl4030_init+0x0/0x20() returned 0 after 29 msecs calling twl4030_pwrirq_init+0x0/0xf8() initcall twl4030_pwrirq_init+0x0/0xf8() returned 0 after 0 msecs calling twl4030_usb_init+0x0/0x1e8() <3>irq 56: nobody cared (try booting with the "irqpoll" option) [<c002cd14>] (dump_stack+0x0/0x14) from [<c006f9fc>] (__report_bad_irq+0x38/0x88) [<c006f9c4>] (__report_bad_irq+0x0/0x88) from [<c006fc5c>] (note_interrupt+0x210/0x270) r5:c0336820 r4:00000000 [<c006fa4c>] (note_interrupt+0x0/0x270) from [<c0070868>] (handle_level_irq+0x94/0xf0) [<c00707d4>] (handle_level_irq+0x0/0xf0) from [<c0028048>] (__exception_text_start+0x48/0x64) r5:c0336820 r4:00000038 [<c0028000>] (__exception_text_start+0x0/0x64) from [<c00285b0>] (__irq_svc+0x30/0x80) Exception stack(0xc7c1dd78 to 0xc7c1ddc0) dd60: 00000020 c0354f60 dd80: c0354f60 00000000 00000002 c0354f60 0000000a 00000001 c7c5d800 00000001 dda0: 00000001 c7c1dddc c7c1dde0 c7c1ddc0 c0050ec0 c0050b44 20000113 ffffffff r7:00000001 r6:0000000a r5:d8200000 r4:ffffffff [<c0050b00>] (__do_softirq+0x0/0xb8) from [<c0050ec0>] (irq_exit+0x48/0x8c) r7:00000001 r6:00000000 r5:c03363f8 r4:00000025 [<c0050e78>] (irq_exit+0x0/0x8c) from [<c002804c>] (__exception_text_start+0x4c/0x64) r5:c03363f8 r4:00000025 [<c0028000>] (__exception_text_start+0x0/0x64) from [<c00285b0>] (__irq_svc+0x30/0x80) Exception stack(0xc7c1de18 to 0xc7c1de60) de00: c7c5d800 000001e2 de20: d8070000 0000601f c7c5d800 c7c5d800 c0344c3c 00000001 c7c5d800 00000001 de40: 00000001 c7c1de74 c7c1de78 c7c1de60 c0195be8 c019593c 60000013 ffffffff r7:00000001 r6:c0344c3c r5:d8200000 r4:ffffffff [<c0195914>] (omap_i2c_idle+0x0/0x68) from [<c0195be8>] (omap_i2c_xfer+0x26c/0x284) r5:c7c5d800 r4:00000001 [<c019597c>] (omap_i2c_xfer+0x0/0x284) from [<c0193284>] (i2c_transfer+0x88/0x9c) [<c01931fc>] (i2c_transfer+0x0/0x9c) from [<c0196780>] (twl4030_i2c_write+0xc0/0xe8) r7:00000001 r6:00000000 r5:c0344c48 r4:c0344ac8 [<c01966c0>] (twl4030_i2c_write+0x0/0xe8) from [<c01967d0>] (twl4030_i2c_write_u8+0x28/0x30) [<c01967a8>] (twl4030_i2c_write_u8+0x0/0x30) from [<c0197e14>] (twl4030_i2c_write_u8_verify+0x20/0x9c) [<c0197df4>] (twl4030_i2c_write_u8_verify+0x0/0x9c) from [<c01982b0>] (twl4030_i2c_access+0x120/0x150) r6:00000000 r5:c7c59a60 r4:00000000 [<c0198190>] (twl4030_i2c_access+0x0/0x150) from [<c001a93c>] (twl4030_usb_init+0x18c/0x1e8) r5:c7c59a60 r4:00000001 [<c001a7b0>] (twl4030_usb_init+0x0/0x1e8) from [<c0008928>] (kernel_init+0xa0/0x218) r6:00000000 r5:00000000 r4:c0024000 [<c0008888>] (kernel_init+0x0/0x218) from [<c004ec70>] (do_exit+0x0/0x5fc) <3>handlers: <3>[<c0195f58>] (omap_i2c_isr+0x0/0x308) <0>Disabling IRQ #56 <3>i2c_omap i2c_omap.1: controller timed out <3>i2c_omap i2c_omap.1: controller timed out <3>twl4030_usb: i2c write failed, line 422 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
