My machine is DELL Inspiron 510m laptop. Before everything was OK. Now the kernel hangs for a minute during bootup between the messages "input: AlpsPS/2 ALPS GlidePoint as /class/input/input2" and "Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 U TC)." During the bootup nothing is printed during the hang, but dmesg contains this at that point: i2c_adapter i2c-0: bus is not idle. status is 0xff i2c_adapter i2c-0: found normal entry for adapter 0,

What do these messages mean? What should I do to get rid of the delay? CL< "
