Lexar NM790 4TB SSD keeps crashing my fresh install of Ubuntu 24.04

I recently upgraded my SSD on my laptop. The SSD is a 4TB Lexar NM790. I used a similar 2 TB drive in another Lenovo laptop without issue.

Dell XPS 15 7590 Manufacturer firmware is fully patched. I am unaware of any firmware updates for the SSD.

$ sudo dmidecode -s bios-version
1.28.0

$ sudo udisksctl status

    The solution was to add:

    nvme_core.default_ps_max_latency_us=0 to boot line for the kernel.

    That is in /etc/default/grub file the line GRUB_CMDLINE_LINUX_DEFAULT should look something like:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=0"

    Then after updating /etc/default/grub, run the following command:

    sudo update-grub

    The /proc/cmdline is:

    BOOT_IMAGE=/boot/vmlinuz-6.8.6-060806-generic root=UUID=3abde92a-afef-478c-a16d-ff136ce7ab9e ro nvme_core.default_ps_max_latency_us=0

    To get your computer to boot, you might need to edit grub when it first boots by adding nvme_core.default_ps_max_latency_us=0 after ro

    (Updates to be added)
