I did an installation of current TW on a new HD. Laptop is having 8GB RAM and a 960 GB SSD (Yes, got me a new one - Kingston this time, after Samsung Evo died 1 month after the 3yr warranty period - and Samsung proofed that they are not consumer oriented. But thats a different story...)
Partition proposal was: 2GB - Swap 40GB - btrfs root 840GB - XFS home
2GB swap with 8GB RAM does not sound healthy for hibernation - should the proposal not be at least the RAM size?>> As the owner of a 1024 GB Samsung EDO 850, your report is not heartening!
On the ThinkPad-Linux mailing list, a day before, a user reported the same problem with the same disk. You may be able to mount it one more time, but afterwards you cant get anything out of a broken SSD....>
Having swap be 1/4 of RAM size does seem a bit small. Memory is compressed when hibernating, thus the amount of disk space used will depend on your load, but 1/2 of RAM sounds safer.
On your system, did you mount your partitions with the noatime option? That reduces the number of disk writes. I also made the swappiness value be low.
I did it on the old disk with EXT4 - for XFS and btrfs I have not checked if this option still exists. To what did you set the swappiness?
I used to have it set at 10. When I checked now, it is set to 60; however, I almost never see any swapping. Like you, I also have 8 GB of RAM.
Do you have a reference to the ThinkPad ML thread? My quick search did not find anything that looked germane.

Thanks for that. It was an interesting read. It makes you wonder how the driver could fail to load the boot information, yet have the rest of the file structure available. For the record, here is a selected portion of the smartctl output for my disk: Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0 9 Power_On_Hours 0x0032 098 098 000 Old_age Always - 7289 12 Power_Cycle_Count 0x0032 098 098 000 Old_age Always - 1030 177 Wear_Leveling_Count 0x0013 099 099 000 Pre-fail Always - 17 179 Used_Rsvd_Blk_Cnt_Tot 0x0013 100 100 010 Pre-fail Always - 0 181 Program_Fail_Cnt_Total 0x0032 100 100 010 Old_age Always - 0 182 Erase_Fail_Count_Total 0x0032 100 100 010 Old_age Always - 0 183 Runtime_Bad_Block 0x0013 100 100 010 Pre-fail Always - 0 187 Reported_Uncorrect 0x0032 100 100 000 Old_age Always - 0 190 Airflow_Temperature_Cel 0x0032 066 048 000 Old_age Always - 34 195 Hardware_ECC_Recovered 0x001a 200 200 000 Old_age Always - 0 199 UDMA_CRC_Error_Count 0x003e 100 100 000 Old_age Always - 0 235 Unknown_Attribute 0x0012 099 099 000 Old_age Always - 246 241 Total_LBAs_Written 0x0032 099 099 000 Old_age Always - 24652115271 My disk has written 24.6 TB of data and has a wear leveling count of 99%. The numbers look good as the on-line expected lifetimes range from 150 to 800 TB. On the other hand, a test of the EVO 840 ran for 200 TB before it failed, but your disk failed after only 19.6 TB! Scaling would have mine fail at 39 TB. I think it may be time to look for special sales of SSD drives and purchase a replacement if I see a particularly good buy. As I currently have about 400 GB on that drive, perhaps a 2 TB drive should be my next purchase. Those are pricey at about $630, but the 1 TB drive is about $50 less than it was in April 2016.
