	The range for the T1, T3 and T3 timers in above table is given in seconds and the idle timeout in minutes. However note that the procfs and sysctl interfaces actually used miliseconds rsp. seconds starting Linux 2.6.17. Before that the values for T1, T2 and T3 were measured in the unit which the kernel was running internal interrupt timer. For Linux 2.4 and older running on i386 MIPS and a few other architectures that was 100Hz (so time was given in units of 100th of a seconds that is multiple of 10ms), some Linux 2.4 Suse kernels however were running at 1000Hz (so AX.25 timings were in units of 1ms), any Linux version on Alpha was always running at 1000Hz except on ''Rawhide'' which were running at 1200Hz (thus making the timing values multiple of 0.833ms). Too complicated? Upgrade to Linux 2.6.17 or newer.		The range for the T1, T3 and T3 timers in above table is given in seconds and the idle timeout in minutes.

			Again the units of time for the T0, T1, T2, T3, Holdback and idle timers were changed to miliseconds in Linux 2.6.17
