PowerCenter Pro 210mhz 604e, 224MB RAM, Linux 2.4-pre11 (rsync from Paul 12/8)

I was removing multiple files from my hfs drive, when I hit the BUG() at
line 236 in /usr/src/linux/include/linux/dcache.h:

static __inline__ struct dentry * dget(struct dentry *dentry)
{
        if (dentry) {
                if (!atomic_read(&dentry->d_count))
                        BUG();
                atomic_inc(&dentry->d_count);
        }
        return dentry;
}
