(Reuters) – Data center computers with the newest Intel Corp chips
could restart more often than normal due to problems with the
patches issued to repair the call security Specter and Meltdown
defects, the company said on Wednesday.
Intel confirmed that patches for security flaws can cause

The Skylake and Kaby Lake processors, said Navin Shenoy, general

Kaby Lake chips are the company's most recent offer.
Last week, Intel said it had received reports that its security
patches were causing problems in the systems with their old Broadwell
and Haswell chips.
Shenoy said that Intel had issued patches for 90 percent of Intel
chips released in the last five years, but that the company had
"More work to do". He also said that the company would send
initial versions of fixes for patches with errors to customers by
"We have reproduced these problems internally and we are doing
progress towards identifying the root cause, "Shenoy wrote.
On January 3, Intel confirmed that the defects of Specter and Meltdown

Spectrum failure affected almost all modern computing devices,
including those with Intel chips, Advanced Micro Devices Inc
and ARM Holdings.
Intel on Wednesday also quantified how much of a performance hit
the patches cause the customers of the data center. For common tasks
how to run web servers, the patches caused a 2 percent
slowdown, Intel said. Another test that simulated online
transactions in a stockbroker showed a deceleration of 4 percent,
The company said.
For some types of jobs that involve servers that store large
