Bisection says: git-ipwireless_cs.patch GOOD # git-x86.patch git-x86-fixup.patch git-x86-arch-x86-math-emu-errorsc-fix-printk-warnings.patch git-x86-drivers-pnp-pnpbios-bioscallsc-build-fix.patch git-x86-fix-doubly-merged-patch.patch git-x86-export-leave_mm.patch BAD and that's where bisection comes to a halt... Time to bisect through git-x86, or somebody got a better idea? Looking at the commits listed in git-x86.patch, I didn't see anything that jumped out, but I'm pretty sure the problem is in there somewhere...
