Hi everyone!

With latest bc, kernel compilation seems to hang as soon as bc is invoked
by kernel compilation procedure; this issue is not present if I revert to
previous bc version.

Would you suggest to start from scratch?


No.  There is some problem.  My build hangs also with bc running at 100%.
  Investigating.


It's a change in behavior in the new bc version.  This is a workaround:

Before make, run:

sed -ri 's/(\$\(CONFIG_HZ\))/"\1;"/' Kbuild

What the command is doing for most systmes is:

  echo 1000 | bc -q ...

Until bc or the kernel is changed, what is needed is:

  echo 1000; | bc -q ...
