[SunHELP] problem with E 450 server loading 2.6

[Vivek Kestur]

Hi,

 We have a problem with installing Solaris 2.6 on two our E 450 machines. It
simply doesn't seem to like 2.6
 When i say boot cdrom on the OK prompt, it gives the following error.

 Boot device: /pci at 1f,4000/scsi at 2/disk at 6,0:f File and args: 
SunOS Release 5.6 Version Generic_105181-05 [UNIX(R) System V Release 4.0] 
Copyright (c) 1983-1997, Sun Microsystems, Inc. 
panic[cpu1]/thread=0x10404040: recursive rw_enter, lp=10417348 wwwh=10404044
waiters=0 thread=10404040 
rebooting... 
Resetting ... 
 However i am able to load Solaris 8 on it without any problem. I knew there
is a problem  with E3500/E4500
 loading 2.6, so i went ahead and tried the 
	 limit-ecache-size
  on the E 450, but i am still getting the same error, enclosed herewith is
the details 
  Sun Enterprise 450 (2 X UltraSPARC-II 480MHz), No Keyboard 
 OpenBoot 3.20, 2048 MB memory installed, Serial #12885353. 
 Ethernet address 8:0:20:c4:9d:69, Host ID: 80c49d69. 

 please help
