Message:

enable kernel console output in case of kernel panic

  • the panic message might still be slightly unreadable due to the framebuffer driver optimizations (we don't waste time with full screen redraw), but at least you know that something bad happened and this issue can be tackled later
  • let's hope that enabling the kernel console cannot make things worse in the panicking kernel (especially with respect to the kernel/uspace interrupt handler priorities switch)
