[SunHELP] RE: SunHELP digest, Vol 1 #799 - 2 msgs

Steve,

>From the error you sent below:
	CPU0 Ecache Writeback Data Parity Error: AFSR 0x00000000.00800004
AFAR
	 0x000001fe.01800800

This is a known E-cache bug for 220R with 2-MB cache CPU and possibly on
4-MB cache CPU.
Once It happened on a CPU, It would not happen again. If you have 2 CPU, you
may get two
crashes at some point of time. There is a temporary fix by applying a latest
kernel patch.
Sun just came out the kernel patch for Sol. 2.7 on December 2000. Just down
load from SunSolve
for the Patch 106541-14 which is the kernel patch for Sol. 2.7.

Regards,

- Trung -

I have heard that sun ultra cpu memory can't catch double bit parity
errors. This can cause undetected data corruption and will cause the box
to crash at some point.

However I don't know what ultra cpu's this applies to.  You should ask sun
about this.  They do have a fix.

The cause for these cases would really be sun spots and solar storms.

Hi all,

I know it's off topic, but URGENT.
Does anybody have a tool to reset the administrative
password on an NT4 box or can point me to some.
Thanks a lot,
Wolfgang
