| |
Hi, there is a very simple one-line change to 2.1.123-pre1 that allows my system to boot into 2.1.124-1. My system is a UP PPro 165 with an EIDE drive and a NE2000-clone PCI card.
The change that has been posted so far, while identifying where the problem lies, isn't really the CORRECT change, since its just a reversion. To show that the new approach basically works (for example, without locking the kernel), simply search for the definition of 'unlazy_fpu' in include/asm-i386/processor.h, and change if (tsk->flags & PF_USEDFPU) { \ to if (1) { \ .
I suspect that when unlazy_fpu is first called, (during the init process) tsk->flags is not set but should be set, so the 'unlazy-ing' is not done. Does that sound like a plausible thing to fix for a CORRECT patch?
