Debug this beautiful panicked kernel !
* Stuff I don't remember * stuff * merge * merge * Step 0 : InitTerms() is the bug * Debug stuff * Step 1 : StartPanic is the real problem * Step 1 : StartPanic is the real problem * Step 1 : StartPanic is the real problem * Step 1 : In StartPanic is the real problem * Step 1 : In StartPanic is the real problem * Step 1 : In StartPanic is the real problem * Step 1 : In StartPanic is the real problem * Step 1 : In StartPanic is the real problem * Step 1.5 : \n was a problem * Step 2 : Well... It was a 'sleepy' problem * Step 2 : Well... It was a 'sleepy' problem * Step 2.1 : GetPanicStr is an array * Step 2.2 : Now panic accept 8 chars * Ok then !
