I'll keep you posted about the end result. I managed to encounter a problem
with User Mode Linux that is known:
do_syscall_stub : ret = -12, offset = 1052680, data = 09b80008
do_syscall_stub: syscall 192 failed, return value = 0xfffffff4, expected
return value = 0x1cff8000
syscall parameters: 0x1cff8000 0x1000 0x7 0x11 0x3 0xd464
Failed to flush page for address 0x1cff8000
Apparently, this scary error, which causes the offending process to terminate,
is the result of an insufficiently large value in /proc/sys/vm/max_map_count.
Since I don't have huge amounts of memory by modern standards, I'm used to
occasional problems with UML, and I guess that some of the build tasks are
quite demanding.
Hopefully, I'll be able to complete the build of GCC 5.4, which is the thing
that repeatably causes this. Then we'll see what happens.
Thanks once again!
Paul
