Linux 5.1 kernel hit by SSD TRIM bug which causes massive data loss

[NumLock21]

Why only samsung ssds and not others, or they are just saying it because most people use a samsung ssd, so they jumped into the conclusion samsund ssd are affected.

Samsung uses a queue TRIM implementation in most of their firmware that behaves badly with Linux, and has previously been blacklisted. I can't find the current list at the moment but this was a commit in 2015 about Samsung TRIM issues https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/ata/libata-core.c?id=9a9324d3969678d44b330e1230ad2c8ae67acf81

Was it samsung that was reponsible for the bad commit?

So anyone running linus don't get a samsung drive. Got it!

Ironically enough, I'm running one that is blacklisted at the moment with Linux (840 EVO), it just doesn't support all TRIM functions.

Same for Linux. If you want support for LTS from the big distros, they are charging you enterprises pricing.

Nope, as a simple consumer i cannot get the LTS version of windows...

Yes you can, you need to register yourself as a business to Microsoft and go through the channel, as a business, to get it.

Lucky, using Pop OS, Ubuntu based.

@Sauron yeh I got that it was a security measure, but windows could argue the same thing, instead of being a kernel panic.

could they have found a way to avoid bringing down the whole thing even as a security risk issue.

 

"That's a bit drastic... wouldn't that cause certain data loss instead of a small chance of it?"

yes and no, defintely a major data loss, but it would also mean companies would have to re-hire people instead of replacing them with robots for everything.

Im a great believer in Technology should assist us, not take over for us.

 

I'll leave the testing thing alone, other to say that the Qand A does not appear to be quite as good as it used to be, that doesnt mean there werent issue's before, but the latest seem to be pretty massive, regardless of OS

I really should look into this Samsung TRIM issue a bit more.   Everything here is on Samsung SSDs and I'm moving it all over from Win7 to Linux later this year. 

Never noticed any issues with the Laptop's drive in the 3 or so years that I've had that one on Mint, but the desktops are where the important info is at.

The safest security measure imo would be always make backups of your important data in cloud services...

 

GNOME desktop has a feature which can make cloud backups of your home folder weekly, with a service you choose (Google drive, Dropbox etc) but should work on other desktops as well

...no, a kernel panic is something completely different. I'm pretty sure you can restart the DE and be just fine. Regardless I'd rather kernel panic than have my system pwned - but windows doesn't only kernel panic for security reasons.

Oh please, if that's your problem blame the exploitative nature of capitalism, not technology.
