This helps prevent the random device from being so com- pute-bound that it takes over all processing ability. A value of 0 (zero) is treated as infinity, and will only allow the kernel to pause if the queue is empty. Only values in the range [0..20] are accepted. if i try to read/set this setting, sysctl returns: sysctl: unknown oid 'kern.random.sys.burst' what's wrong, my kernel or the manpage? [6.1-RELEASE/i386]
