It looks like this change caused it, this also seems to cause a null ptr error on startup, which I thought was unrelated. 909657615d9b3ce709be4fd95b9a9e8c8c7c2be6 is the first bad commit commit 909657615d9b3ce709be4fd95b9a9e8c8c7c2be6 Author: Christoph Hellwig Date: Thu Apr 6 15:36:32 2017 +0200 scsi: libsas: allow async aborts We now first try to call ->eh_abort_handler from a work queue, but libsas was always failing that for no good reason.

The problem still exists with 4.15.0-041500rc6-generic Prior versions were also affected. I initially suspected faulty hardware, and for months did not care about the contents of the disks. I only looked back at the problem when I finally replaced the hard disk.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 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". Thanks in advance.
