Hema HK 4f9edd2d7e usb: musb: Fix the crash issue during reboot ... Below crash observed with commit 7acc6197b7 (usb: musb: Idle path retention and offmode support for OMAP3) during board reboot. The musb clock was disabled when musb_shutdown() was called by platform_drv_shutdown in which there are register accesses. call pm_runtime_get_sync() and pm_runtime_put_sync() in the musb_shutdown function. / # [ 172.368774] Unhandled fault: imprecise external abort (0x1406) at 0x400f0000 [ 172.376190] Internal error: : 1406 [#1] SMP [ 172.380554] last sysfs file: /sys/devices/platform/omap/omap_i2c.4/i2c-4/i2c-dev/i2c-4/dev [ 172.389221] Modules linked in: [ 172.392456] CPU: 0 Tainted: G W (2.6.38-06671-geddecbb #33) [ 172.399475] PC is at do_raw_spin_unlock+0x50/0xc0 [ 172.404418] LR is at _raw_spin_unlock_irqrestore+0x24/0x44 [ 172.410186] pc : [<c069bfdc>] lr : [<c085a7f8>] psr: 60000093 [ 172.410186] sp : ee993e40 ip : c0d00240 fp : bea9cf14 [ 172.422241] r10: 00000000 r9 : ee992000 r8 : c04b2fa8 [ 172.427703] r7 : 00000000 r6 : c0fa46c0 r5 : ef966124 r4 : ef966124 [ 172.434539] r3 : ef92cbc0 r2 : ef92cbc0 r1 : 00000000 r0 : ef966124 [ 172.441406] Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user [ 172.448974] Control: 10c5387d Table: ae8d804a DAC: 00000015 [ 172.454986] Process init (pid: 1094, stack limit = 0xee9922f8) [ 172.461120] Stack: (0xee993e40 to 0xee994000) [ 172.465667] 3e40: a0000013 c085a7f8 ef966124 a0000013 c0fa46c0 c0761ab4 c0761a70 ef95c008 [ 172.474273] 3e60: ef95c014 c06e2fd0 c06e2fbc c06dea90 00000000 01234567 28121969 c04fccb4 [ 172.482849] 3e80: 00000000 c04fcd04 c0a302bc c04fce44 c0a02600 00000001 00000000 c085cd04 [ 172.491424] 3ea0: 00000000 00000002 c09ea000 c085afc0 ee993f24 00000000 00040001 00000445 [ 172.499999] 3ec0: a8eb9d34 00000027 00000000 00000000 00000000 c0a56a4c 00000000 00000000 [ 172.508575] 3ee0: 00000002 60000093 00000000 c0519aac 00000002 00000080 00000000 c0550420 [ 172.517150] 3f00: 00000000 00000002 ee970000 c0a56a3c c0a56a20 00000002 c0a56a3c 00000000 [ 172.525726] 3f20: c0a56a3c 0000000a c1580e00 c0a56a20 00000002 c0a56a3c c1580e00 c0a56a20 [ 172.534301] 3f40: ef92cbc0 c05173a0 00000001 ef92cbc0 c0576190 c04e3174 20000013 c0517324 [ 172.542877] 3f60: ef815c00 ee90b720 c04e3174 c0576190 00000001 ef92cbc0 c04b2f00 ffffffff [ 172.551483] 3f80: 00000058 c0517324 00000000 00000000 ffffffff 00000000 00000000 ffffffff [ 172.560058] 3fa0: 00000058 c04b2de0 00000000 00000000 fee1dead 28121969 01234567 00000000 [ 172.568634] 3fc0: 00000000 00000000 ffffffff 00000058 00000000 00000001 400aa000 bea9cf14 [ 172.577209] 3fe0: 000ea148 bea9c958 000aa750 40225728 60000010 fee1dead 00000000 00000000 [ 172.585784] [<c069bfdc>] (do_raw_spin_unlock+0x50/0xc0) from [<c085a7f8>] (_raw_spin_unlock_irqrestore+0x24/0x44) [ 172.596588] [<c085a7f8>] (_raw_spin_unlock_irqrestore+0x24/0x44) from [<c0761ab4>] (musb_shutdown+0x44/0x88) [ 172.606933] [<c0761ab4>] (musb_shutdown+0x44/0x88) from [<c06e2fd0>] (platform_drv_shutdown+0x14/0x18) [ 172.616699] [<c06e2fd0>] (platform_drv_shutdown+0x14/0x18) from [<c06dea90>] (device_shutdown+0x74/0xb4) [ 172.626647] [<c06dea90>] (device_shutdown+0x74/0xb4) from [<c04fccb4>] (kernel_restart_prepare+0x24/0x38) [ 172.636688] [<c04fccb4>] (kernel_restart_prepare+0x24/0x38) from [<c04fcd04>] (kernel_restart+0xc/0x48) [ 172.646545] [<c04fcd04>] (kernel_restart+0xc/0x48) from [<c04fce44>] (sys_reboot+0xfc/0x1d8) [ 172.655426] [<c04fce44>] (sys_reboot+0xfc/0x1d8) from [<c04b2de0>] (ret_fast_syscall+0x0/0x3c) [ 172.664459] Code: e3c3303f e594200c e593300c e1520003 (0a000002) [ 172.670867] ------------[ cut here ]------------ Signed-off-by: Hema HK <hemahk@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>		2011-04-13 11:51:28 +03:00
