Hi,
I currently have some trouble with a amd64 HEAD build machine.
This machine cross compile for an ARMv6 host.
During the compilation, objcopy enter in an infinite loop. The process is stuck
(unkillable) in "RUN" state:

The only thing a can get for now is the kernel backtrace via "procstat -kk
93219", that I run in loop
There are some of the data:

The "common" part is the vfs_bio_getpages that seems to endless loop.
What I can do to bring more info for that issue ?
Best regards
