Titolo: Trovato bug nel processore Intel Copermine

 Questa volta Intel rischia grosso se la notizia verrą confermata in tutta
la sua gravitą.
Howard Ha informs me that a bug has been uncovered in Intel's new Coppermine
PIII's. Luckily, Intel plans to eradicate this bug in the next stepping:
Some Coppermine processors intermittently seize up between power-up and
power-down cycles. The problem applies only to some Coppermine processors.
The rumours, which we have now confirmed, were posted on JC's pages,
yesterday.
An Intel representative confirmed there is a problem with Coppermine
processors and said the bug will be fixed in the next stepping (Intel calls
chip bugs errata.) In the meantime, it is tightening up its quality control
checks.
He said: "An intermittent issue which resulted in failure to start the boot
process was reported in lab environments on a very small number of
"Coppermine" (0.18-micron) Pentium® III processor-based systems. The issue
does not result in any data corruption."
Intel, he says, has discovered the root cause of the problem and has
tightened its testing procedures to minimise problems. That probably means a
further quality control test at fabrication time.

Intel, now Dell acknowledge Coppermine bug
Chip giant Intel has confirmed that it found a bug (erratum) in its .18
micron Coppermine processor which has caused it to tighten up its quality
control procedures.
And now Dell US has confirmed that it has put a temporary stop on shipping
its GX110 PC range because of the problem.
Some Coppermine processors intermittently seize up between power-up and
power-down cycles. The problem applies only to some Coppermine processors.
The rumours, which we have now confirmed, were posted on JC's pages,
yesterday.
An Intel representative confirmed there is a problem with Coppermine
processors and said the bug will be fixed in the next stepping (Intel calls
chip bugs errata.) In the meantime, it is tightening up its quality control
checks.
He said: "An intermittent issue which resulted in failure to start the boot
process was reported in lab environments on a very small number of
"Coppermine" (0.18-micron) Pentium® III processor-based systems. The issue
does not result in any data corruption."
Intel, he says, has discovered the root cause of the problem and has
tightened its testing procedures to minimise problems. That probably means a
further quality control test at fabrication time.
He added: "This issue is considered as errata and will be eliminated in a
future stepping. The Coppermine ramp is healthy. OEMs have been shipping
0.18-micron Pentium® III processor based systems in all frequencies."
The representative from Dell US said that it had initiated the stop ship
notice just before the Thanksgiving holiday last week. The actual stop ship
too effect at the beginning of this week.
"This is a dual due diligence move," she said. "We're implementing a screen
for the erratum. To date, we haven't experienced any problems and we're just
implementing it as an extra precaution."
She said that the Optiplex GX110 was sold to corporate and institutional
customers, who expected quality machines that worked every time, which is
why Dell had taken the precaution.
The Dell move must mean that other PC manufacturers are either already
taking steps to screen chips and products, or are about to.
The GX110 does not ship with Rambus memory, the representative said. Dell is
still testing and qualifying this type of memory for use with its flagship
corporate product.
The errata list on Coppermines is already rather long for a new family of
processors. You can download the latest list from Intel's site as a PDF
document to check it out for yourself. The latest erratumnotbug does not yet
seem to have found its way onto the list.
The news could not have come at a worse time for Intel, already beleagured
by other problems and stiff competition from AMD. It could also go some way
towards explaining why Coppermine chips have been as scarce as hen's teeth.

E' dai Pentium 60 che Intel ha deciso di non smentirsi e di proporre chip
buggati. E' per questo che costano di più, hanno la sorpresa....

 Dove posso trovarne?
Prova sul sito della Intel: sono anni che produce merda!
Più biologiche di così! ^_^

quindi...
anche il 90?
ma non erano solo i 60 e 66??? (quelli sul mitico sockettone a 5V!)
mhh davvero non ricordo..

Posso confermare che c'era anche il P90...SIGH! :-(((

Ed il 100 da cui vi scrivo, che tra l'altro va a 133 *senza ventola*


Beh allora io devo essere proprio sfigato perche` il mio amato Linux
durante il boot della workstazione in ufficio mi scrive
"Intel Pentium with F0 bug - workaround enabled".
Ed e` un 200 mmx.
Cos'e`, un altro bug che ha avuto meno pubblicita`?

Cos'e`, un altro bug che ha avuto meno pubblicita`?
forse si riferisce un bug molto singolare
bastavano 5 righe in C per bloccare il processore 
tutti, dal P60 al 233mmx solo i Ppro e PII (stessa archittettura)
erano... ops pardon, SONO immuni 
il freeze era totale
