Hello gentlemen, I've discovered an interesting failure on some machine running 4.7. It's so weird so I'd very unlikely notice it at all, but thanks to top(1): when launched, instead of displaying some useful figures it exits with an error: "top: nlist failed". >From quick look it appears that kvm_nlist() returns NULL for nlst[0].n_type. Strange, ignoring; next exit point is: "top: kvm_read for _ccpu: Bad address" Something bad happens: kernel virtual memory symbol table becomes unreadable, so kvm calls fail... But system runs all right, has completed buildworld today... Source of the problem is objcopy(1), i.e. wiping symbols from kernel to make it more compact. This shouldn't be a problem, but libkvm holds another point of view... --- Regards, Rhett __________________________________________________ Yahoo!
