---------------------------+------------------------------
Compiling native GHC triggers this panic all the time. However, the
spinlock command in KDL always says it's not locked, and only one core is
running (other three are in idle).
I don't really know how to reduce to a test case, nor know which threads
to look at.
However, to reproduce using GHC (it'll continually trigger the KDL when
resuming), can use the following steps:
{{{
wget https://www.haskell.org/ghc/dist/7.8.3/ghc-7.8.3-src.tar.xz
wget http://haiku.jessicah.org/working-ghc-cross-install.zip
wget https://raw.githubusercontent.com/nick8325/haiku-ghc/master/ghc-
patches/0001-Haiku-patches.patch
tar xJQf ghc-7.8.3-src.tar.xz
extract working-ghc-cross-install.zip into /system/non-packaged
cd ghc-7.8.3
patch -Np1 < ../0001-Haiku-patches.patch
setarch x86
./configure --prefix=/boot/home/test-ghc
make -jN # multiple jobs seems to trigger it more often than without
}}}
You'll also need updated binutils/gcc4 packages (I've just uploaded, and
available in hrev48162 for gcc2h).
