Hi,
I am on a Thinkpad 25. When copying from the integrated nvme to an externally connected USB3 Sandisk Extreme Portable SSD using dd, the system locks up (completely with stuttering sound and the screen going black after 10 secs) at the 98 GB mark.
Command I am running:
dd if=/dev/nvme0n1 of=/dev/sda bs=1M status=progress
Kernel output: kern1.log attached, system freezes
Alternatively, when trying to copy to an image on the file system: dd if=/dev/nvme0n1 of=/mnt/sandisk/nvme0n1.img bs=1M status=progress
Kernel output: kern2.log attached, system freezes
It works perfectly fine, when I run dd if=/dev/zero of=/dev/sda and dd if=/dev/nvme0n1 of=/dev/null, way beyond the 98GB mark. Also badblocks does not report any errors on /dev/sda.
Kernel version: Ubuntu 5.4.0-37.41-generic 5.4.41
lspci -vnvn: attached
lsusb -vvv: attached
Cheers!
