When using rt73usb driver for my wireless usb rt73 based card the system crashes. This doesn't happen immediately after the module is loaded. It happens when the software tries to bind the card with a wireless network (retrieve i.p. for the card via dhcp e.t.c.). There is another weird thing going on with the usb. If I start my system with my usb mouse (15d9:0a33) there will be a kernel panic when trying to move the mouse. Removing the mouse (no mouse plugged in, or only one ps2 mouse) doesn't solve the problem. The system will crash when asking for an i.p. from the router. If I plug another mouse I have (046d:c51a) the system doesn't kernel panic. Removing my rt73 based wireless card or disabling the network tools that uses this card solves the problem. I can't fully understand if this is an issue that concerns only the rt73usb driver or is a generic issue for the usb kernel driver. The system doesn't alway kernel panic. Some time it produces an Oops message and will panic some time later. Usually when trying to start X. Steps to reproduce: Try to boot a system using rt73usb without any pointing device or with the 15d9:0a33 mouse.

That sounds icky...I'm not really sure where to start...
I am not really sure that the particular driver causes the fault. I could be something that concerns the kernel usb driver. I was surprised by the fact that the system works with another mouse plugged and doesn't work with no mouse at all. The only sure thing thing is that when rt73usb driver isn't used everything works. Related infos: http://bbs.archlinux.org/viewtopic.php?id=74622
I have to be a more general usb related issue. More and more user are having problem with kernel panic related with a usb device. I want to have a look to possible changes made to the usb general modules. Did you found anything related considering rt73? At least to exclude this one.
same happens here, using various kernels (2.6.30, 2.6.31-rc2-git8 , git9) the problem seems to go away from one build to the next, and then reappear. it always happens when starting the network, attaching the kernel Oops log.

Have a look to the following bug. http://bugzilla.kernel.org/show_bug.cgi?id=13681
that bug was closed as irreproducible by you. im still experiencing these Oopses. usually after several hours of uptime. more rarely, during a wlan0 connection. what i can find in common with all these oopses, is that the last sysfs file is /net/wlan0/statistics/collisions. im too much of a noob to further debug this, although im quite confident in patching and building custom kernels. this particular Oops was triggered after a 'lsmod' command. (lsmod froze) the Oops reports look like this one: ----- [ 3372.630492] BUG: unable to handle kernel paging request at 000cfa0b [ 3372.630505] IP: [<c10735ac>] m_show+0x9c/0x1a0 [ 3372.630523] *pde = 00000000 [ 3372.630529] Oops: 0000 [#1] PREEMPT SMP [ 3372.630539] last sysfs file: /sys/devices/pci0000:00/0000:00:1d.7/usb1/1-2/1-2:1.0/net/wlan0/statistics/collisions [ 3372.630548] Modules linked in: ipv6 snd_usb_audio snd_usb_lib snd_rawmidi gspca_zc3xx gspca_main videodev v4l1_compat usbhid hid fan mmc_block cpufreq_ondemand arc4 acpi_cpufreq ecb freq_table fuse snd_hda_codec_si3054 snd_seq_dummy snd_hda_codec_realtek sdhci_pci sdhci snd_seq_oss rt73usb crc_itu_t iTCO_wdt iTCO_vendor_support snd_hda_intel snd_seq_midi_event snd_seq snd_seq_device evdev mmc_core 8139too ohci1394 snd_hda_codec snd_pcm_oss snd_mixer_oss uhci_hcd ehci_hcd psmouse rt2x00usb rt2x00lib mii ieee1394 i2c_i801 snd_hwdep snd_pcm snd_timer snd soundcore snd_page_alloc serio_raw led_class input_polldev battery ac thermal button processor usbcore sg mac80211 cfg80211 rtc_cmos rtc_core rtc_lib ext3 jbd mbcache sr_mod cdrom sd_mod ata_piix ata_generic pata_acpi libata scsi_mod [ 3372.630705] [ 3372.630713] Pid: 4800, comm: lsmod Not tainted (2.6.31-rc5-git2-custom #1) Everex StepNote Series [ 3372.630722] EIP: 0060:[<c10735ac>] EFLAGS: 00210292 CPU: 1 [ 3372.630731] EIP is at m_show+0x9c/0x1a0 [ 3372.630737] EAX: 00000000 EBX: f5ebbd20 ECX: 00000000 EDX: 00000000 [ 3372.630744] ESI: f8b35180 EDI: 000cfa0b EBP: f8b352c0 ESP: f618febc [ 3372.630752] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [ 3372.630760] Process lsmod (pid: 4800, ti=f618e000 task=f61d4000 task.ti=f618e000) [ 3372.630766] Stack: [ 3372.630770] f5ebbd20 c13d5303 f8fbc14c 0000dd84 f8b35184 f618ff18 e76a1664 e76a1664 [ 3372.630787] <0> c134e908 f5ebbd20 f8b35184 0000009f c110264f 00000001 c257e520 f618ff90 [ 3372.630805] <0> f00fd800 00000035 000003cb f5ebbd48 b8001035 00000000 00000032 00000000 [ 3372.630824] Call Trace: [ 3372.630839] [<c110264f>] ? seq_read+0x25f/0x450 [ 3372.630850] [<c11023f0>] ? seq_read+0x0/0x450 [ 3372.630861] [<c112f8f9>] ? proc_reg_read+0x79/0xc0 [ 3372.630871] [<c10e5495>] ? vfs_read+0xc5/0x1b0 [ 3372.630881] [<c112f880>] ? proc_reg_read+0x0/0xc0 [ 3372.630890] [<c10e569f>] ? sys_read+0x5f/0xb0 [ 3372.630901] [<c1003c93>] ? sysenter_do_call+0x12/0x28 [ 3372.630907] Code: 10 31 c0 81 c5 3c 01 00 00 39 ef 74 2d 66 90 8b 47 08 89 1c 24 c7 44 24 04 03 53 3d c1 83 c0 0c 89 44 24 08 e8 36 ec 08 00 8b 3f <8b> 07 0f 18 00 90 39 ef 75 da b8 01 00 00 00 8b 96 d4 00 00 00 [ 3372.631005] EIP: [<c10735ac>] m_show+0x9c/0x1a0 SS:ESP 0068:f618febc [ 3372.631018] CR2: 00000000000cfa0b [ 3372.631060] ---[ end trace 0755589f17a3f813 ]---

The problem seems to be quite random. After a clean install about 20 days ago I have only received the Ooops message and a kernel panic 4~5 times. The first 10 days or so after continuous reboots an extensive use of the computer there was no sign of the problem. http://bugzilla.kernel.org/show_bug.cgi?id=13681
could you try and build a kernel with the .config settings i pasted above enabled? i would provide the entire .config but i did strip out many device drivers. if you still want it, let me know. i still havent suffered from a single Oops.
I will give it a try.
Closed due to lack of response...
