B.1. Special system/CPU-specific bugs/problems

• SIGILL (signal 4) on P3 using 2.2.x kernels:

  Problem: kernel 2.2.x doesn't have proper (working) SSE support

  Solution: upgrade kernel to 2.4.x

  Workaround: ./configure --disable-sse

• General SIGILL (signal 4):

  Problem: you compiled and run MPlayer on different machines (for example compiled on P3 and running on Celeron)

  Solution: compile MPlayer on the same machine where you will use it!

  Workaround: You can forget all this by configuring with the --enable-runtime-cpudetection option or you can disable particular CPU instruction sets with more specific options (like --disable-mmx, --disable-3dnow, etc).

• Crashes when dumping streams:

  Problem: core dump

  Solution: Don't panic. Make sure you know where your towel is.
