BKernel::TeamSignalEvent::DoDPC: failed to acquire spinlock for a long time
|Reported by:||jessicah||Owned by:||axeld|

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).
