[Bug 925760] Re: Constant warnings from the kernel: Test WP failed, assume Write Enabled
I have the same problem since I had my first Linux Mint 16 and now turned into Linux Mint 17 (Qiana - 32bit) the problem is still there (Ubuntu 14.04 i believe). Below, is my workaround which may benefit others too. I have experimented a bit with the User Interface, more specifically the Control Center - Disks (menu in the Mate). There, is a Power Off menu choice of the Realtek Mass Storage device (ie. by pci builtin Card reader, usually empty). And voila - the kernel messages stopped ! :-) It would be nice if one could power down specific ones, by will. I have found some solutions (not working for me) mostly like tweaking files in the Drivers settings (/sys/bus/usb/devices path). These were more or less Linux version dependent, and did not work for me. Instead, I carried on experimenting, and using the same Control Center - Disks I found a small button to edit Mount options which opened the dialog as I have attached a screenshot of. If I in there specifically said 'Automatic Mount Options' to OFF, then I permanently seems to avoid the kernel messaged flooding the system log. So I stay with this workaround, until further. ** Attachment added: "Mate - Control Center - Disks - Mount Options" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/925760/+attachment/4261844/+files/Automatic%20Mount%20Options%20sdb.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925760 Title: Constant warnings from the kernel: Test WP failed, assume Write Enabled To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/925760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 925760] Re: Constant warnings from the kernel: Test WP failed, assume Write Enabled
For a permanent workaround, create the file /etc/modprobe.d/ums- realtek.conf with the following content: options ums_realtek ss_en=0 or execute this command: sudo sh -c 'echo "options ums_realtek ss_en=0" > /etc/modprobe.d/ums- realtek.conf' I think this bug could be declared fixed once the ss_en option is disabled by default. This can be done either by shipping a modprobe conffile or by changing the default value of the option in the kernel source. The 'ss_en' switch controls 'selective suspend', e.g. suspending parts of the card reader which are not used. Typically only one card slot is in use at any time, so disabling would slightly decrease power consumption when a card is inserted. When there is no card, the reader would power down through the normal USB suspend mechanism. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925760 Title: Constant warnings from the kernel: Test WP failed, assume Write Enabled To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/925760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 925760] Re: Constant warnings from the kernel: Test WP failed, assume Write Enabled
I am running ubuntu 12.04 LTS 64 bit on a Dell Vostro 3550 and I have experienced this issue as well. However, the problem has been SOLVED by simply removing the factory installed dummy from the SD slot. Apparently, the relevant driver is designed to detect a SD module via the slot plug-in switch activation. As such, any object with the right shape that could activate this switch will be detected as a valid SD module. The ensuing syslog messages are a result of the automout trying (every ~ 45 seconds) to mount what is in fact an invalid device. Should these messages be generated with an empty SD slot, I would suspect the slot plug-in switch to be faulty ("on" all the time). Consequently, I do not believe this to be a kernel bug, although it may be possible to find a more reliable way to detect a valid SD module for the device driver.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug. If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

Aha - it turns out the second workaround (inserting an SD card) stopped working when I re-inserted the little inert plastic insert that fills in the SD card hole when you're not using it. So the real workaround is to pull that out and leave it out, or to remove the kernel module. This also suggests what is going on - for some reason the driver now seems to be constantly trying to figure out what is going on with the inert plastic insert.

Here are some snippets from around each of the three messages: * ... read write protect setting, if possible - called only in sd_revalidate_disk() sd_read_write_protect_flag(struct scsi_disk *sdkp, unsigned char *buffer) { if (sdp->skip_ms_page_3f) { sd_printk(KERN_NOTICE, sdkp, "Assuming Write Enabled\n"); ... if (!scsi_status_is_good(res)) { sd_printk(KERN_WARNING, sdkp, "Test WP failed, assume Write Enabled\n"); ... sd_read_cache_type - called only from sd_revalidate_disk() if (scsi_sense_valid(&sshdr) && sshdr.sense_key == ILLEGAL_REQUEST && sshdr.asc == 0x24 && sshdr.ascq == 0x0) /* Invalid field in CDB */ sd_printk(KERN_NOTICE, sdkp, "Cache data unavailable\n"); else sd_printk(KERN_ERR, sdkp, "Asking for cache data failed\n"); -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925760 Title: Constant warnings from the kernel: Test WP failed, assume Write Enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/925760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 925760] Re: Constant warnings from the kernel: Test WP failed, assume Write Enabled
Thank you for taking the time to file a bug report on this issue. However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request. We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not. You can update to the latest development kernel by simply running the following commands in a terminal window: sudo apt-get update sudo apt-get upgrade If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released. If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging. Thank you for your help, we really do appreciate it. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Tags added: kernel-request-3.2.0-13.22 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925760 Title: Constant warnings from the kernel: Test WP failed, assume Write Enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/925760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 925760] Re: Constant warnings from the kernel: Test WP failed, assume Write Enabled
Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.3 kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.3-rc2 fixed the issue, the tag would be: 'kernel-fixed- upstream-v3.3-rc2'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance. ** Tags added: needs-upstream-testing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925760 Title: Constant warnings from the kernel: Test WP failed, assume Write Enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/925760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
