We've checked whole TRM and found > nothing wrong yet :( > we tried the same driver for Omap zoom platform ,I too dont see any interrupts from this driver.I also observe that duing bluetooth file transfer i see the below crash from twl4030-madc driver. Once i disable the madc driver in kernel configuration my Bluetooth works fine,while Bluetooth has nothing to do with i2c or madc driver.A similar crash is also observed during GFX operation Regards, Ram. here is the log: i2c_omap i2c_omap.1: controller timed out waiting for start condition to finish twl: i2c_write failed to transfer all messages Unable to handle kernel NULL pointer dereference at virtual address 00000044 pgd = c0004000 [00000044] *pgd=00000000 Internal error: Oops: 17 [#1] PREEMPT last sysfs file: /sys/devices/platform/kim/firmware/kim/loading Modules linked in: bt_drv st_drv CPU: 0 Not tainted (2.6.32-14922-g86eec44 #1) PC is at dev_driver_string+0x0/0x38 LR is at twl4030_madc_write+0x2c/0x4c pc : [<c01f2bc0>] lr : [<c01fede0>] psr: a0000013 sp : cf02bf08 ip : 0000738f fp : 00000000 r10: cf002cc8 r9 : c038a839 r8 : 00000000 r7 : cf02bf3c r6 : c04edff8 r5 : 00000007 r4 : cf227a00 r3 : 00000007 r2 : 02070002 r1 : 00000007 r0 : 00000000 Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c5387d Table: 8d23c019 DAC: 00000017 Process events/0 (pid: 5, stack limit = 0xcf02a2e8) Stack: (0xcf02bf08 to 0xcf02c000) bf00: 00000006 00000002 c04edff8 c01fef6c cf179680 cf179680 bf20: cf02a000 cf002cc0 c028a5a8 00000000 cf002cc8 c028a5dc 00000000 00000200 bf40: cf020001 00000000 cf020d40 00000017 cf0213c0 c007f1dc 00000000 cd277e40 bf60: cf02bf94 c036e58c cd0bac9c cf020ed4 60000013 cf002cc0 cf002cbc cf02a000 bf80: cf002cc0 c01dcc00 cf002cc0 00000000 cf179684 c0076ff4 cf02bfcc 00000000 bfa0: cf020d40 c007a660 cf02bfa8 cf02bfa8 cf023f60 cf02bfd4 cf023f60 cf002cc0 bfc0: c0076e8c 00000000 00000000 c007a334 00000000 00000000 cf02bfd8 cf02bfd8 bfe0: 00000000 00000000 00000000 00000000 00000000 c0035f80 00000000 00000000 [<c01f2bc0>] (dev_driver_string+0x0/0x38) from [<c01fede0>] (twl4030_madc_write+ 0x2c/0x4c) [<c01fede0>] (twl4030_madc_write+0x2c/0x4c) from [<c01fef6c>] (twl4030_madc_conv ersion+0x74/0x288) [<c01fef6c>] (twl4030_madc_conversion+0x74/0x288) from [<c028a5dc>] (twl4030_bk_ bci_battery_work+0x34/0x60) [<c028a5dc>] (twl4030_bk_bci_battery_work+0x34/0x60) from [<c0076ff4>] (worker_t hread+0x168/0x214) [<c0076ff4>] (worker_thread+0x168/0x214) from [<c007a334>] (kthread+0x7c/0x84) [<c007a334>] (kthread+0x7c/0x84) from [<c0035f80>] (kernel_thread_exit+0x0/0x8) Code: c04edd3c c04eddcc c042bef5 c040d709 (e5903044) -- 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
