nvme data corruption

[-]

booted opi5 via nvme one day and the boot screen mentions about btrfs partition missing even tho it was using ext4 partition. booted via sdcard and the root partition is entirely missing on the nvme. the boot partition is still there and working. not sure if relevant but the previous time i shut the opi5 down, i forgot to unplug it and it was plugged in for about an hour after shutdown with the red led and fan on. the nvme is kingspec which while cheap doesnt seem to have that many bad reports online that i can find (the boot partition was fine so i suspect kingspec isnt at fault). the power adapter is a 25w phone charger w/ pd/qs; it hasnt exhibited any weird behavior (like random shutdowns) thus far.

 

i just chalked it up to my set of parts that led to this data corruption until on the opi discord someone mentioned the 160 kernel halved the speed of the nvme. i recall my device was recently updated to the 160 kernel. lost about 100gb of data so im definitely going back to 110 kernel builds.
