gptzfsboot regression, "panic: bd_strategy: 114688 bytes I/O not multiple of block size"

[Malte Gräbner]

Hello Folks,

I've got a Dell Server with a H330 with 2 zpools which isn't able to boot anymore. 
There is a 4x Disk zpool with 2 SSD LOG devices and a zroot zpool with 2 ssds. 

There is done nothing special with the zpools or the loader. 
Its a 11.1 RELASE. The only reference to this problem I can find is: 

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=201082

But im not even able to get past the btx loader. I can import the pools via bsd installer iso shell and the pools are all fine. 

Are there any suggestions how to bring this thing up again ? 

PS: zdb |grep ashift
