Hi,

can anybody explain what's exactly wrong, please ?

It looks like QBB0 backplain issue, but who knows .....

Brief Description:
Duplicate tag parity error detected in the DTAG of SoftQbb0 (HardQbb0)

Callout ID:
Theory Code : 0x03C003000007AF05
HQBB.Ent.Flt : 0.24.3

Severity:
1

Reporting Node:
zacerp

Full Description:
The Dtag control register (DTAG_CONTROL) indicated a parity or double bit ECC
error in the duplicate tag store. Before the Dtag writes information in its tag
rams it generates parity (dtag1) or ECC (dtag2). Therefore the fact that we did
get this error on a read means the problem is caused by the tag rams or by the
Dtag control logic. Dtag rams and the control logic are part of the QBB
backplane. The error was detected in Duplicate Tag 0 block 3. This error causes
a system fault condition.
