Though the issue is not related to the strongswan, hope you can still check my questions, thanks!
I don't know what "non-vanilla comcerto crypto driver" mean. Is that crypto for encrypting the IP package to be ESP pacakge?
I google searched the comcerto cypto, it seems that comcerto cypto is a Hardware of Mindspeed, and I'm using the Mindspeed
board T3300, is that mean the host system is using the Hardware method to encrypt the IP package to be ESP and there's an
error with the driver of the HW comcerto of Mindspeed?
Namely, if I use the software method for crypto, then there's no this issue? If I use the software method, the crypto method had
been provided by the Linux kernel already?

As it is the Linux kernel that crashes, I don't think it is directly related to strongSwan, which is userland only.

Looks more like a bug in your non-vanilla comcerto crypto driver in the kernel.
