Greetings,
I'm having issues with both an internal M.2 SATA (SanDisk SD6PP4M-256G-1006) and an SSD inside an external SATA/USB enclosure (Samsung 850 EVO 120G). My apologies if these are unrelated and should be split. For now, I'll post the errors together. I've googled the errors but don't find much in the way of a definitive issue or resolution. Examples:
- exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen: nothing standing out to me (possibly blacklisting some modules, but not really the error I have either)
- failed command: READ DMA EXT: all the posts I find feature a {DRDY ERR} in the logs, which I don't have.
- device reported invalid CHS sector 0: try replacing cables, drive failure possible, libata.force=noncq (done long ago)
- blk_update_request I/O error: set BIOS to AHCI or better drive cooling (my BIOS is already set to AHCI and this is external anyway?), noncq (again, done already), failing drive
- Synchronize Cache(10) failed: report of faulty usb stick, suggestion to run ntfsfix
I should note that this computer is < 2mos old. The Samsung 850 EVO is maybe 3-4 weeks old. I can run smartctl again if the output is really desired, but I highly doubt both drives are failing. They have both passed the longtest run within the past week. I'm applying trim via the systemctl service, have turned off UAS (per this method) for the external drive (that was causing some real unrecoverable freezes on high writes e.g. rsync restoration of a backup), and have noncq passed via syslinux.
I'm looking for suggestions on how to troubleshoot further. The momentary freezes are just a minor annoyance, but make me wonder if something deeper is wrong with my setup. The auto-dismounts are more concerning, as the drive is encrypted with Truecrypt to share data with Windows and I'm prompted to run CHKDISK when I boot into Windows, indicating the dismounts are not clean. I'd hate to ruin a nice drive's lifespan or lose my data due to bad dismounts on an encrypted drive. Thanks for any suggestions.
Internal SATA SSD
Occasionally, I get momentary system freezes. Things become unresponsive like chrome or thunar, and recover after perhaps 5-10 seconds. I see errors like this via dmesg:

For the external drive, the primary issue I experience is automatic dismounting sometimes upon suspend/resume cycles:

Were you able to fix this problem on HP Z Book 15?

@edhex: forgot about this post! I didn't get any replies and when it kept happening I started a new thread here. You can read through that one if you'd like. The most helpful posts might be the later ones, but so you know my most successful solution has been to append "pci=nomsi" to my syslinux.cfg kernel line. I haven't had any freezes and no messages like the above. There's links to the kernel error documentation where I noted that this option was recommended for the errors with "(timeout)" in them.
I plan to leave it like this for a couple weeks and if I still have no issues I'll try the other potentially less-all-encompassing options (like I reference in this post on that thread.
Hope that helps!
