Hi,
I am seeing an issue with next-20201211 with USB3380[1] based PCIe card

lspci output.

From: Mian Yousaf Kaukab
Instead of piggybacking on ACPI_PROCESSOR_DEVICE_HID, convert the driver
to a proper platform driver with its own ID. Driver will only be probed
when cppc-cpufreq device is available.
Fixes: 28f06f770454 ("cppc_cpufreq: replace per-cpu structures with lists")
From: Mian Yousaf Kaukab
Since commit 28f06f770454 ("cppc_cpufreq: replace per-cpu structures with
lists"), cppc-cpufreq driver doesn't check availability of PSD data before
registering with cpufreq core. As a result on a ThunderX2 platform when
CPPC is disabled from BIOS, kernel
e_put_sync()
call.

I am seeing following kernel crash on Jetson TX2. Board is flashed with
firmware bits from L4T R32.4.2 with upstream u-boot. Crash always
happens while decompressing initrd. Initrd is approximately 80 MiB in
size and compressed with xz (xz --check=crc32 --lzma2=dict=32MiB).
Crash is not observed if
Export MODULE_DEVICE_TABLE since the driver can be built as a module.

Some more info here can be useful. For example why you are removing LS2088A

GENERIC_CPU_VULNERABILITIES provide a common way to figure out if a
system is affected by vulnerabilities like meltdown and other variants
