Re: current kernels hang on i386 and amd64

The patch for kern/38707 didn't work for me.

I applied the patch, then started a ' -j8' and about 25 minutes later the machine just locked up solid. Only recourse was to use the reset button and reboot.

As an additional datapoint, the above-mentioned hang occurred while building on a quad-core AMD Phenom with src and obj directories on locally-attached disk.

If I NFS-export those file systems and run the exact same on my dual-core Athlon 64 X2 the build takes twice as long as normal but runs to completion without errors.

So seems to definitely be related to load. Either that or I'm getting bitten by the "more than 4GB RAM bounce buffer" problem, but the symptoms of that are usually less severe - just random failures of gcc or other build tool.

Is there an easy way to disable the extra RAM (other than opening up the box and removing DIMMs)?
