[Bug 1823346] Re: SD card stays locked even when unlocked
This may be a regression introduced by this commit: commit 20bd1d026aacc5399464f8328f305985c493cde3 Author: Jeremy Cline Date: Tue Mar 6 21:47:32 2018 + scsi: sd: Keep disk read-only when re-reading partition If the read-only flag is true on a SCSI disk, re-reading the partition table sets the flag back to false. To observe this bug, you can run: 1. blockdev --setro /dev/sda 2. blockdev --rereadpt /dev/sda 3. blockdev --getro /dev/sda This commit reads the disk's old state and combines it with the device disk-reported state rather than unconditionally marking it as RW.

I'm sorry, I don't know.

[Bug 1823346] Re: SD card stays locked even when unlocked
Sorry, trying to follow your instructions, but some competency problems here: I did install and test with v5.1-rc4 kernel. Behaviour is exactly the same. (oddly, this was the easy bit.) Finally worked out how to add a tag. But now: 1) my dmesg appears to be broken with this kernel. Just hundreds of lines all saying the same, eg: [ 693.835558] cma: cma_alloc: alloc failed, req-size: 1 pages, ret: -12 and 3) bug already says "confirmed" I'm confused. ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823346 Title: SD card stays locked even when unlocked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1823346/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v5.1-rc3 kernel [0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed”, and attach dmesg. Thanks in advance.
