According to internal papers that The Register has seen IBM is having big trouble delivering Meltdown/Spectre patches to their customers. Evidently they haven't been able to set up processes to respond to issues after patching and are writing an Excel spreadsheet to track actions taken. I feel sorry for IBM customers if all of this is true. A once proud company is a shell of its former self. The documents also report that patches for the twin CPU bugs are failing on Windows due to interactions with antivirus tools. That’s a known issue others have encountered. The documents also say some Red Hat Enterprise Linux servers aren’t rebooting after patching, which is of more concern given that Red Hat developed its own Meltdown/Spectre patches.
