I cannot reproduce similar firmware crashing issues myself.

However, this can be reproduced easily by other teammates and verified
with machines from the cert pool. While this is already not the first
time we have such crashes that highly depend on the environment in
testing, and we're always recommended to use the highest firmware API
supported by kernel, I don't think I should keep blocking this by the
excuse that I don't have the right environment.
