Hi.

Here's the description of a problem I'm having with kernels >= 2.4.19 on my ASUS A7M266-D.

PROBLEM: with RedHat 7.2, on a ASUS A7M266-D, dual Athlon MP1500+, kernel 2.4.19, right at the beginning of rc.sysconfig during boot hwclock reports wrong time. Usually the time that is reported is the nearest 20th minute of the hour.

The problem *does not* occurr if instead of a USB keyboard a PS2 keyboard is attached, OR with kernels <= 2.4.18, OR if a key is pressed right after POST and before GRUB loads its stage1.

Could please someone direct me to the right person to help me debug this? I can't figure out if it is a problem with the USB drivers, the RTC code, or something else.

Here below is the information on my system.

Thanks
Luca
