Linux Kernel Daily: Ethernet Probe Crash and Late R-C Stabilization
A network shaper locking check in 7.3 release candidate 1 crashes Ethernet probe on drivers that attach a PHY before setting device operations, driving a ten-driver fix series. Late-cycle SoC, KVM, IOMMU, and resume fixes round out a quiet networking pull ahead of R-C 8.

Good morning, it's Friday, October 16th, 2026.
Our lead story: one locking assertion is crashing Ethernet drivers at boot, and it accounts for most of today's networking fixes.
The cause is a check added for network shapers that reads device operations during P-H-Y attach. If shaper support is enabled and a driver connects to the PHY before it assigns those operations, probe hits a null pointer dereference. That breakage appeared in 7.3 R-C 1. The series merged in commit 052b892 moves the…
Second theme: resume, concurrency, and large-packet corner cases. Commit AA07285 fixes a suspend-resume soft lockup on ST-M-MAC where a pending R-G-M-I-I status storms the interrupt after a MAC reset. The fix clears that status on interrupt handling, tested on Helios 64 and Odroid H-C 4. Commit 7b16eb9 fixes a…
Finally, late-cycle stabilization. SoC fixes add fans and P-C-I-E root ports on Tegra 264 to prevent overheating, repair a P-C-I clock divider regression on T-I DRA 7, and fix sensor probing on Beagle-V Fire. I-O-M-M-U reverts a check removal that caused G-P-U regressions, while K-V-M fixes a false panic in async…
What's next: if you maintain out-of-tree Ethernet, test probe with shaper…
