MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 5468 Lines: 131 Hi! When I switched from 2.6.18 to 2.6.19-rc1 processes started to get killed during resume due to an oops in __wake_up_common on my arm pxa272 device (htc magician). The patches I used are at http://userpage.fu-berlin.de/~zabel/magician/magician-patches-2.6.19-rc3-20061025.tar.bz2 Is there any information in those reports that could help me find the issue? I have no idea how to debug this, so I'd appreciate any hint. <4>Stopping tasks: =============| <4>Suspending console(s) <4>resume: <4>CCCR = 02000408 <4>CLKCFG = 00000009 <4>MSC0 = 7ff085a2 <4>MSC1 = 18801880 <4>MSC2 = 16607ff0 <4>magician_udc_command(0) <4>usb usb1: root hub lost power or was reset <3> usbdev1.2_ep00: PM: resume from 0, parent 1-1 still 2 <3>hci_usb 1-1:1.0: PM: resume from 2, parent 1-1 still 2 <3> usbdev1.2_ep81: PM: resume from 0, parent 1-1:1.0 still 2 <3> usbdev1.2_ep02: PM: resume from 0, parent 1-1:1.0 still 2 <3> usbdev1.2_ep82: PM: resume from 0, parent 1-1:1.0 still 2 <3>hci_usb 1-1:1.1: PM: resume from 2, parent 1-1 still 2 <3> usbdev1.2_ep03: PM: resume from 0, parent 1-1:1.1 still 2 <3> usbdev1.2_ep83: PM: resume from 0, parent 1-1:1.1 still 2 <3> hci0: PM: resume from 0, parent 1-1:1.0 still 2 <4>Restarting tasks...<6>usb 1-1: USB disconnect, address 2 <4> done <6>udc: USB reset <1>Unable to handle kernel paging request at virtual address a2f0c000 <1>pgd = c2ef8000 <1>[a2f0c000] *pgd=00000000 <4>Internal error: Oops: f5 [#1] <4>Modules linked in: hci_usb ohci_hcd usbcore magician_ts leds_magician hidp l2cap bluetooth g_ether corgi_bl <4>CPU: 0 <4>PC is at __wake_up_common+0x1c/0x78 <4>LR is at __wake_up+0x4c/0x78 <4>pc : [] lr : [] Not tainted <4>sp : c2eddd90 ip : a2f0c000 fp : c2edddbc <4>r10: 000d8000 r9 : c2edddf0 r8 : 80000013 <4>r7 : c0000008 r6 : 00000001 r5 : 00000003 r4 : c0000008 <4>r3 : 00000000 r2 : 00000001 r1 : 00000003 r0 : c0000008 <4>Flags: Nzcv IRQs off FIQs on Mode SVC_32 Segment user <4>Control: 397F <4>Table: A2EF8000 DAC: 00000015 <4>Process sh (pid: 888, stack limit = 0xc2edc260) <4>Stack: (0xc2eddd90 to 0xc2ede000) <4>dd80: c01187b8 c0000008 00000003 00000001 <4>dda0: c2edddf0 80000013 c382b220 000d8000 c2edddec c2edddc0 c002f140 c002dbe4 <4>ddc0: c2edddf0 00000005 000000bf c028bdc0 00000000 c028bdc0 c2ed8b60 c394b5f8 <4>dde0: c2edde04 c2edddf0 c0048970 c002f100 c028bdc0 00000000 c2edde1c c2edde08 <4>de00: c005830c c0048948 c2ed8800 00000001 c2edde54 c2edde20 c0064d80 c00582c4 <4>de20: a0000013 c38f8800 00005402 c2ed8800 a2eee0df 00000000 c2ed8b60 c394b5f8 <4>de40: 000d8000 c2ef8000 c2eddebc c2edde58 c0065e4c c0064d14 c2ef8000 c382b260 <4>de60: a2eee0df c01de0ac 00000000 00000001 00000800 c382b220 c001f160 c2ef8000 <4>de80: c2eddeac 00000360 c0103cb0 c002e128 c0103e04 ffffffff c382b254 c394b5f8 <4>dea0: c3e68d60 c382b220 c2eddfb0 000d80f0 c2eddefc c2eddec0 c00226a0 c00655c0 <4>dec0: c022d6c0 a0000013 c2eddef4 0000081f c00763ac ffffffff c01dccd0 0000081f <4>dee0: c2eddfb0 000d80f0 00001008 401ed000 c2eddfac c2eddf00 c0022958 c00225c8 <4>df00: c2eddf24 c3cc6de0 c2eddf2c c2eddf18 c01a611c c002e128 c2edc000 00000000 <4>df20: c2eddf5c c2eddf30 c003f3b0 c002e128 c0045ea8 c3cc6de0 bec187b0 c2eddf60 <4>df40: 0000001c 000000ae c001afa8 bec187b0 00000014 00000000 bec187b0 c003f4b8 <4>df60: 00000000 14000000 4010b740 08000000 00000000 0001e0bc 14000000 4010b740 <4>df80: 08000000 00000000 000c50d4 ffffffff 401ee0b4 401ee0b4 401ee07c 00000063 <4>dfa0: 00000000 c2eddfb0 c001ada8 c0022928 000d70e0 00001038 00002040 401ee404 <4>dfc0: 00000438 401ee0b4 401ee0b4 401ee07c 00000063 00001008 401ed000 00001002 <4>dfe0: 000d80e8 bec189b0 00000003 401431e8 20000010 ffffffff 00000000 00000000 <4>Backtrace: <4>[] (__wake_up_common+0x0/0x78) from [] (__wake_up+0x4c/0x78) <4>[] (__wake_up+0x0/0x78) from [] (__wake_up_bit+0x34/0x3c) <4> r8 = C394B5F8 r7 = C2ED8B60 r6 = C028BDC0 r5 = 00000000 <4> r4 = C028BDC0 <4>[] (__wake_up_bit+0x0/0x3c) from [] (unlock_page+0x54/0x60) <4>[] (unlock_page+0x0/0x60) from [] (do_wp_page+0x78/0x5cc) <4> r4 = 00000001 <4>[] (do_wp_page+0x0/0x5cc) from [] (__handle_mm_fault+0x898/0x9d8) <4>[] (__handle_mm_fault+0x0/0x9d8) from [] (do_page_fault+0xe4/0x230) <4>[] (do_page_fault+0x0/0x230) from [] (do_DataAbort+0x3c/0xa0) <4>[] (do_DataAbort+0x0/0xa0) from [] (ret_from_exception+0x0/0x10) <4> r8 = 00000063 r7 = 401EE07C r6 = 401EE0B4 r5 = 401EE0B4 <4> r4 = FFFFFFFF <4>Code: e24dd004 e590c000 e59b9004 e1a07000 (e59c5000) <4> <6>note: sh[888] exited with preempt_count 2 <6>udc: USB reset <6>usb0: full speed config #1: 100 mA, Ethernet Gadget, using CDC Ethernet <3>pxa2xx-udc pxa2xx-udc: pxa27x_ep_disable, ep1in-bulk not enabled <3>pxa2xx-udc pxa2xx-udc: pxa27x_ep_disable, ep2out-bulk not enabled <6>usb 1-1: new full speed USB device using pxa27x-ohci and address 3 <6>usb 1-1: configuration #1 chosen from 1 choice Some more Oops messages (not only page faults, but all of them ending in __wake_up_common) are at http://userpage.fu-berlin.de/~zabel/magician/oops.txt thanks Philipp - 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/
