sparstation SLC boot problems

[joost@pc47.mpn.cp.philips.com]

Hi,

I have two sparcstation SLC's that crash when booting the december
tftpboot.img.  What happens is that the kernel begins booting and just
after it detects 4 serial ports (I only have one dual port connector), the
screen starts to shake for a second and I'm thrown back at the PROM prompt
with the message:

  Watchdog reset
  Window Underflow

Both SLC's have 16 MB of RAM, which tests ok at power-on self test and
when tested manually from the PROM prompt. PROM is version 1.4.

Cheers,


Joost
