Hi,
The recent kernels seem to have a problem with AMDs Elan SC410 processor,
which basically is an 386 core. After starting the kernel the system
simply reboots; snapshot of boot process as following:
----------8<----------
Linux version 2.4.15-greased-turkey (robert@callisto) (gcc version 2.95.3

Ok.

At this moment the machine reboots. Same with 2.4.16; 2.4.14 and earlier
kernels worked without any problem.
Ideas?
