--- Comment #1 from Dexuan Cui <decui@microsoft.com> ---
Thanks pete for reporting the issue! No need for you to test UFS, as I thin=
k we
can reproduce the issue with UFS, and our internal testing team is trying to
narrow down the issue by bisecting.

Especially, symptom #2 happens to the Hyper-V vmbus driver, which hasn't be=
en
updated for 8 months, except for the PTI patch.

I suspect something unusual, like unexpected memory corruption, is happening
here.
