Thinkpad X270 / Toshiba KXG50ZNV1T02: system freezes under heavy I/O

I have a problem with a Thinkpad X270 that has a Toshiba KXG50ZNV1T02 NVME drive installed.
Whenever my system does heavy disk operations, the laptop completely freezes. Most of the times, it doesn't even respond to REISUB. The actual amount of disk I/O necessary to trigger this is unpredictable: sometimes it's an update weighing 1GB, sometimes it's a 12GB write. Both reads and writes trigger the issue, but it's much more common with writes.

While I'm currently running Arch Linux, the same problem was occurring under Fedora 39.

I have already tried to update the disk firmware to AADA4107, which doesn't solve the issue. What could be the problem here?

This is my detailed system info:

fw-rev: AADA4105 temp: 27.9 C scheme: MBR

I don't know if this has any bearing but the drive is configured as MBR. Are you on a UEFI system? It looks like you are since you have a partition with vfat for boot. Best to use GPT for UEFI system.
https://wiki.archlinux.org/title/partit … tion_Table
Reformat the drive as GPT., re-install and see if it improves.

EDIT: Just found out it's possible to convert from MBR to GPT:

Thanks. I'm quite surprised that the disk is MBR, I was pretty sure it had been installed as GPT. However, why could it be influence the issue?

I didn't say it will but simply to try it out. GPT is just more modern and part of UEFI which means it is designed for your motherboard so perhaps data communication is optimized as I see it.

Re: Thinkpad X270 / Toshiba KXG50ZNV1T02: system freezes under heavy I/O

I have no solution but I have to share that I have problems with my x270 too.

But it mainly happens on windows 10, on which I dual boot. I got BSOD, on some updates with heavy I/O.

It happened only once so far while using archlinux on this x270. the nvme drive completely disappeared prompting a forced reboot. I think it over-heat somehow.
I tried to replace the default basic cooling of the nvme with a bigger thermal pad, but it changed nothing.

My nvme is a samsung something. I think it needs some heavy cooling while under used and under heavy I/O

I still need to check the CPU and clean the inside of the laptop. It is a second-hand laptop...

Re: Thinkpad X270 / Toshiba KXG50ZNV1T02: system freezes under heavy I/O

I noticed that the problem occurs much more quickly with

dd if=/dev/urandom of=test.img bs=1024 count=100M

than with

dd if=/dev/zero of=test.img bs=1024 count=100M

dd if=/dev/zero of=test.img bs=1024 count=100M

That is expected. The first one the computer has to produce randomness but the second one simply rights zero's (chucks them out).
