Problems installing Linux in Ultra Sparc III (clock_probe?)

Hi,
 
  I've tried to install Suse 7.3 in a SunFire 280R Utra Sparc-III
  with no success. I wonder if anybody can give me a hint?
 
  After the boot sequence starts (prior to any installation),
  the process is interrupted with message:
 
  "clock_probe: problem, cannot find bus to search"
 
  I have tracked down that message to arch/sparc64/kernel/time.c
  in function void __init clock_probe(void) . There, variable
  busnd is set to flag value -1 that indicates no bus found.
 
  Are there any success stories of suse-sparc instalation in the same hw ?
  Is there any story of simmilar failure in this or any other platform ?
 
  Since I have not subscribed to this list, I kindly ask you to reply
  also to my personal address <[email protected]>.
 
  TIA
 
  regards,
  Senra
