Title:
System lockup when copying exactly 98 GB from NVME to USB3 device
Status in linux package in Ubuntu:
Confirmed
Bug description:
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!
