Hello!

We have an IBM POWER server (8247-42L) running Linux kernel 5.4.13 on Debian unstable
hosting a big-endian ppc64 virtual machine running the same kernel in big-endian
mode.

When building OpenJDK-11 on the big-endian VM, the testsuite crashes the *host* system
with the following kernel backtrace. The problem reproduces both with kernel 4.19.98
as well as 5.4.13.

Backtrace has been attached at the end of this mail.

Thanks,
Adrian

Paulus,

Something below for you I think


> We have an IBM POWER server (8247-42L) running Linux kernel 5.4.13 on Debian unstable
> hosting a big-endian ppc64 virtual machine running the same kernel in big-endian
> mode.
> 
> When building OpenJDK-11 on the big-endian VM, the testsuite crashes the *host* system
> with the following kernel backtrace. The problem reproduces both with kernel 4.19.98
> as well as 5.4.13.
> 
> Backtrace has been attached at the end of this mail.

> Thanks,
