"The driver was shredding the MIG configuration on any soft reset. We’d wake up to find our A100s split into 7 instances, but only 1 was addressable," the source told us. "This new driver fixes that, but they had to rewrite the MIG scheduler from scratch."
This is an —specifically the unannounced features, the silent performance regressions, and the architectural shifts of the R550+ driver branch (version 555.85.05 and its enterprise siblings). The "Stealth" Update: R555.85.05 Breakdown Two weeks ago, NVIDIA quietly pushed a new Production Branch driver to its developer portal without a typical blog post fanfare. Our analysis of the release notes (or lack thereof) reveals a build that is less about game-ready optimizations and entirely focused on two things: AI inference latency and virtualized memory paging . cuda driver release news exclusive
This is a sleeper feature. The driver now handles split-world memory addressing where the Windows Kernel and the Linux Kernel argue over the same GPU memory. Stability has gone from "crash every hour" to "crash once a week." Speaking with a senior AI infrastructure engineer at a major cloud provider (who requested anonymity due to NDA), we learned that the R555 driver series was internally delayed by four months due to a "catastrophic" bug involving Multi-Instance GPU (MIG) partitioning. "The driver was shredding the MIG configuration on
