Hello, this update freshly announced (not available since days, like 2 weeks) seemed to completely break my CentOS 7 system running on a Dell Precision 7530. when I applied it days ago. Once the new microcode has been applied during the yum update transaction, with other updates like nss, system suddently froze, and no way to reboot. I could boot from a flashdrive and give a look at the boot logs, determine that lots of updated files where 0-byte length on the xfs root partition - and since the nss update was part of the yum update, nothing could boot at all, nss comes w/ libraries that are quite low-level, mostly network-related. I identified the broken files, the broken packages, downloaded them from repositories and unpacked them manually, in order to boot. Once I could boot the system, I reverted the broken yum transaction, re-installed the updates et voila. Since then, I live with a exclude=microcode_ctl-2.1-53.7.el7_7.x86_64 in CentOS-Base.repo file and wonder if I'll give the next update a try.. or not! Anybody w/ similar experience or any thought with regards to this? Regards, -- wwp https://useplaintext.email/ -------------- next part -------------- A non-text attachment was scrubbed...
