Hi all, I got the below GPF when i followed these steps:
0. livecam is running happily 1. disconnect camera 2. reconnect camera 3. close livecam, which has a frozen image. I'm using the m5603-mt9v011 branch with my "Creative WebCam Live! Pro" unfortunately, I didn't have any debug options on, so the output isn't as verbose as it could be. I might try to reproduce it tomorrow with more debugging on. Thanks, d# usb 1-1: USB disconnect, address 4 usb 1-1: new high speed USB device using ehci_hcd and address 5 usb 1-1: configuration #1 chosen from 1 choice general protection fault: 0000 [1] PREEMPT CPU 0 Modules linked in: m5603c videodev v4l2_common v4l1_compat it87 hwmon_vid eeprom ds1621 nvidia(P) parport_pc parport k8temp i2c_nforce2 Pid: 19439, comm: livecam Tainted: P 2.6.24-gentoo-r3 #3 RIP: 0010:[<ffffffff804c0472>] [<ffffffff804c0472>] usb_ifnum_to_if+0x12/0x60 RSP: 0018:ffff81000e0bfe00 EFLAGS: 00010202 RAX: 00000000ffffff8f RBX: ffff81002f46c000 RCX: ffffffff887f559a RDX: 0380002e0005033b RSI: 0000000000000000 RDI: ffff81002f46c000 RBP: 0000000000000000 R08: 0000000000000000 R09: ffff810001e00140 R10: 0000000000000002 R11: 00000000000002a7 R12: 0000000000000000 R13: ffff81001e556600 R14: ffff81003e8a1900 R15: 0000000000000000 FS: 00002b4bc7109c70(0000) GS:ffffffff8074a000(0000) knlGS:00000000f5e0eb90 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00002b4bc6457cb0 CR3: 0000000008c13000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process livecam (pid: 19439, threadinfo ffff81000e0be000, task ffff81003bd68e60) Stack: ffffffff804c8883 ffff810009b30388 ffff81001e556600 ffff81003e8a1900 0000000000000282 ffff8100092ec000 ffff8100092edb48 ffff810009b30388 ffff81001e556600 ffff81003e8a1900 ffffffff887f94e0 0000000000000008 Call Trace: [<ffffffff804c8883>] usb_set_interface+0x53/0x1c0 [<ffffffff887f94e0>] :m5603c:v4l_m5603c_release+0xc0/0xf0 [<ffffffff8028e4c1>] __fput+0xb1/0x1f0 [<ffffffff8028b324>] filp_close+0x54/0x90 [<ffffffff80232fb9>] put_files_struct+0xe9/0x120 [<ffffffff8023460e>] do_exit+0x17e/0x8f0 [<ffffffff80234dad>] do_group_exit+0x2d/0xa0 [<ffffffff8020bb4e>] system_call+0x7e/0x83 Code: 44 0f b6 42 04 45 85 c0 7e f0 48 8b 8a 98 00 00 00 31 ff 48 RIP [<ffffffff804c0472>] usb_ifnum_to_if+0x12/0x60 RSP <ffff81000e0bfe00> ---[ end trace 93c31bedf2361d17 ]--- Fixing recursive fault but reboot is needed! ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
