Re: Kernel Ooops upon USB disconnect of a Western Digital My Passport 1TB drive
Just one more FYI, by blacklisting the ses module, the oops goes away.

Kernel Ooops upon USB disconnect of a Western Digital My Passport 1TB drive
Hello all. On my Thunkpad T420i with 3.18.2 and 3.18.3 kernels, I can reproduce the following behaviour 100% of the time: 1. Connect one of my (NTFS-formatted) WD 1TB 'My Passport' drives via USB. 2. Disconnect the cable. 3. Kernel Ooops. For last entries of the journal (it actually caught the kernel oops one time, I'm amazed) see the photo here: https://dl.dropboxusercontent.com/u/63420/journal.jpg Please note that the drive need not be mounted at all. In fact, this even happens if I stop all graphical and automount services and plug-in and then disconnect the cable. Also, other USB drives and USB flash disks do not exhibit this behaviour... Go figure! If I'm on a console, I can only see the last 45 or so lines of the stack trace (using KVM 1600x900 resolution console). The first lines (along with the initial oops message (caught in the journal) get scrolled off so I cannot post anything). What can I do to further debug this? I'm uncomfortable having any plug-in utility writing to my disk after the crash since I'm using this laptop for work and have crucial data on it. I have also opened a bug here: https://bugzilla.kernel.org/show_bug.cgi?id=92091 Thanks! -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
