Johan Hovold b193b412e6 usb: musb: omap2430: fix kernel panic on reboot ... Cancel idle timer in musb_platform_exit. The idle timer could trigger after clock had been disabled leading to kernel panic when MUSB_DEVCTL is accessed in musb_do_idle on 2.6.37. The fault below is no longer triggered on 2.6.38-rc4 (clock is disabled later, and only if compiled as a module, and the offending memory access has moved) but the timer should be cancelled nonetheless. Rebooting... musb_hdrc musb_hdrc: remove, state 4 usb usb1: USB disconnect, address 1 musb_hdrc musb_hdrc: USB bus 1 deregistered Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa0ab060 Internal error: : 1028 [#1] PREEMPT last sysfs file: /sys/kernel/uevent_seqnum Modules linked in: CPU: 0 Not tainted (2.6.37+ #6) PC is at musb_do_idle+0x24/0x138 LR is at musb_do_idle+0x18/0x138 pc : [<c02377d8>] lr : [<c02377cc>] psr: 80000193 sp : cf2bdd80 ip : cf2bdd80 fp : c048a20c r10: c048a60c r9 : c048a40c r8 : cf85e110 r7 : cf2bc000 r6 : 40000113 r5 : c0489800 r4 : cf85e110 r3 : 00000004 r2 : 00000006 r1 : fa0ab000 r0 : cf8a7000 Flags: Nzcv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user Control: 10c5387d Table: 8faac019 DAC: 00000015 Process reboot (pid: 769, stack limit = 0xcf2bc2f0) Stack: (0xcf2bdd80 to 0xcf2be000) dd80: 00000103 c0489800 c02377b4 c005fa34 00000555 c0071a8c c04a3858 cf2bdda8 dda0: 00000555 c048a00c cf2bdda8 cf2bdda8 1838beb0 00000103 00000004 cf2bc000 ddc0: 00000001 00000001 c04896c8 0000000a 00000000 c005ac14 00000001 c003f32c dde0: 00000000 00000025 00000000 cf2bc000 00000002 00000001 cf2bc000 00000000 de00: 00000001 c005ad08 cf2bc000 c002e07c c03ec039 ffffffff fa200000 c0033608 de20: 00000001 00000000 cf852c14 cf81f200 c045b714 c045b708 cf2bc000 c04a37e8 de40: c0033c04 cf2bc000 00000000 00000001 cf2bde68 cf2bde68 c01c3abc c004f7d8 de60: 60000013 ffffffff c0033c04 00000000 01234567 fee1dead 00000000 c006627c de80: 00000001 c00662c8 28121969 c00663ec cfa38c40 cf9f6a00 cf2bded0 cf9f6a0c dea0: 00000000 cf92f000 00008914 c02cd284 c04a55c8 c028b398 c00715c0 becf24a8 dec0: 30687465 00000000 00000000 00000000 00000002 1301a8c0 00000000 00000000 dee0: 00000002 1301a8c0 00000000 00000000 c0450494 cf527920 00011f10 cf2bdf08 df00: 00011f10 cf2bdf10 00011f10 cf2bdf18 c00f0b44 c004f7e8 cf2bdf18 cf2bdf18 df20: 00011f10 cf2bdf30 00011f10 cf2bdf38 cf401300 cf486100 00000008 c00d2b28 df40: 00011f10 cf401300 00200200 c00d3388 00011f10 cfb63a88 cfb63a80 c00c2f08 df60: 00000000 00000000 cfb63a80 00000000 cf0a3480 00000006 c0033c04 cfb63a80 df80: 00000000 c00c0104 00000003 cf0a3480 cfb63a80 00000000 00000001 00000004 dfa0: 00000058 c0033a80 00000000 00000001 fee1dead 28121969 01234567 00000000 dfc0: 00000000 00000001 00000004 00000058 00000001 00000001 00000000 00000001 dfe0: 4024d200 becf2cb0 00009210 4024d218 60000010 fee1dead 00000000 00000000 [<c02377d8>] (musb_do_idle+0x24/0x138) from [<c005fa34>] (run_timer_softirq+0x1a8/0x26) [<c005fa34>] (run_timer_softirq+0x1a8/0x26c) from [<c005ac14>] (__do_softirq+0x88/0x13) [<c005ac14>] (__do_softirq+0x88/0x138) from [<c005ad08>] (irq_exit+0x44/0x98) [<c005ad08>] (irq_exit+0x44/0x98) from [<c002e07c>] (asm_do_IRQ+0x7c/0xa0) [<c002e07c>] (asm_do_IRQ+0x7c/0xa0) from [<c0033608>] (__irq_svc+0x48/0xa8) Exception stack(0xcf2bde20 to 0xcf2bde68) de20: 00000001 00000000 cf852c14 cf81f200 c045b714 c045b708 cf2bc000 c04a37e8 de40: c0033c04 cf2bc000 00000000 00000001 cf2bde68 cf2bde68 c01c3abc c004f7d8 de60: 60000013 ffffffff [<c0033608>] (__irq_svc+0x48/0xa8) from [<c004f7d8>] (sub_preempt_count+0x0/0xb8) Code: ebf86030 e5940098 e594108c e5902010 (e5d13060) ---[ end trace 3689c0d808f9bf7c ]--- Kernel panic - not syncing: Fatal exception in interrupt Cc: stable@kernel.org Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>		2011-02-17 14:34:17 +02:00
