QEMU throws an error after interrupts are enabled
Posted: Wed Sep 10, 2008 8:55 am
QEMU throws the following error when running my kernel:
I have narrowed the problem, and it happens after interrupts are enabled in main() in main.c.
I have also tried to add hlt:s to the code to the interrupt and exception handlers but the error still comes up.
I would really appreciate even pointing to the place where the error might occur.
Thanks in advance.
BTW the sources are in the tarball
