On my x86_64 Fedora 10 desktop running 188.8.131.52-117.fc10.x86_64, I do the following:
- downloaded kernel-184.108.40.206-117.fc10.src.rpm
- setup an rpmbuild area in my home dir
- rpm -i kernel-220.127.116.11-117.fc10.src.rpm
- cd ~/rpmbuild/SPECS
- rpmbuild -ba kernel.spec
The build runs about 40 minutes and then the machine completely locks up / freezes. It won't respond to a sysrq, and power-cycling is the only option.
This is 100% repeatable. Any ideas what's happening?
