Steps to reproduce: 1. make sure zaurus (with the OZ 3.3.5 rom) is in the cradle and connected 2. modprobe usbnet, either manually or automatically by hotplug, makes no difference 3. ifconfig usb0 192.168.129.200 netmask 255.255.255.255 up 4. route add -host 192.168.129.201 usb0 5. ping 192.168.129.201 -works 6. ssh 192.168.129.201 After a while it always has the oops and afterward ifconfig usb0 says "Device not found" and rmmod usbnet hangs (as in kill -9 doesn't work). $ uname -a Linux debian 2.6.5-1-686 #5 Fri Apr 30 20:26:13 EST 2004 i686 GNU/Linux $ dmesg ... usb0: register usbnet at usb-0000:00:1d.1-2, Sharp Zaurus SL-5x00 drivers/usb/core/usb.c: registered new driver usbnet usb0: no IPv6 routers present hub 2-0:1.0: port 2 disabled by hub (EMI?), re-enabling...<6>usb 2-2: USB discon nect, address 3 usb0: unregister usbnet usb-0000:00:1d.1-2, Sharp Zaurus SL-5x00 usb 2-2: new full speed USB device using address 4 Unable to handle kernel NULL pointer dereference at virtual address 00000004 printing eip: d034e044 *pde = 00000000 Oops: 0000 [#1] PREEMPT CPU: 0 EIP: 0060:[<d034e044>] Not tainted EFLAGS: 00010282 (2.6.5-1-686) EIP is at usb_disable_interface+0x14/0x50 [usbcore] eax: ce4b0bc0 ebx: 00000000 ecx: ce480000 edx: cf77f0a0 esi: 00000001 edi: 00000000 ebp: cf522400 esp: ce481d64 ds: 007b es: 007b ss: 0068 Process khubd (pid: 619, threadinfo=ce480000 task=cf436c00) Stack: 00001388 00000000 00000001 00000001 cf4eee38 cf522400 d034e2c8 cf522400 ce4b0bc0 0000000b 00000001 00000001 00000001 00000000 00000000 00001388 00000000 ce4b0bc0 cf4eee38 cf4eee38 cf21a160 00000001 d1a4d0c1 cf522400 Call Trace: [<d034e2c8>] usb_set_interface+0xb8/0x1a0 [usbcore] [<d1a4d0c1>] get_endpoints+0xb1/0x120 [usbnet] [<d1a4dcaf>] generic_cdc_bind+0xdf/0x240 [usbnet] [<d1a4faf0>] usbnet_tx_timeout+0x0/0x50 [usbnet] [<d1a505ff>] usbnet_probe+0x3df/0x410 [usbnet] [<c016f071>] dput+0x31/0x220 [<d0348081>] usb_probe_interface+0x61/0x80 [usbcore] [<c01f257f>] bus_match+0x3f/0x70 [<c01f25ef>] device_attach+0x3f/0xa0 [<c01f27fb>] bus_add_device+0x5b/0xa0 [<c01f1641>] device_add+0xa1/0x130 [<d034e685>] usb_set_configuration+0x1d5/0x270 [usbcore] [<d0349198>] usb_new_device+0x258/0x3d0 [usbcore] [<d034ab63>] hub_port_connect_change+0x183/0x290 [usbcore] [<d034af37>] hub_events+0x2c7/0x340 [usbcore] [<d034afe5>] hub_thread+0x35/0x100 [usbcore] [<c0109242>] ret_from_fork+0x6/0x14 [<c011cde0>] default_wake_function+0x0/0x20 [<d034afb0>] hub_thread+0x0/0x100 [usbcore] [<c01072ad>] kernel_thread_helper+0x5/0x18 Code: 80 7b 04 00 74 26 31 f6 8d 74 26 00 8b 43 0c 47 0f b6 44 30 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...
