ACPI TAD DRIVER FIXES LAND AS 7.1-RC2 STABILIZES

By RepoJournal · Filed 14:15 UTC on May 1, 2026 · About Linux

The kernel is tightening up core subsystems ahead of 7.1 final, with ACPI, networking, and storage all shipping targeted fixes overnight.

Linus pulled a wave of ACPI patches that address removal ordering bugs in the Time and Alarm Device driver and fix timer computation issues that could cause incorrect RTC behavior [1]. A companion merge swept in four separate ACPI branches [2] including a critical EINJV2 memory error injection fix in APEI, a CPU hotplug inconsistency in the CPPC library, and a quirk for HP OMEN 16 backlight handling. On the network side, the SMB3 client layer [3] got multichannel crediting fixes and allocation improvements in compound operations—high-impact for enterprise NFS users. The sound subsystem [4] landed a data race fix in the PCM OSS layer alongside device-specific quirks for HD-audio and USB-audio controllers. MTD subsystem [5] shipped Winbond octal SPI NAND support and an out-of-bounds fix that affects embedded storage stacks.

Action items

→ Test 7.1-rc2 against your ACPI-dependent hardware, especially laptops with TAD devices torvalds/linux [plan]
→ Retest SMB3 multichannel scenarios if you maintain Windows interop paths torvalds/linux [plan]
→ Monitor PCM OSS audio paths for race condition regressions in testing torvalds/linux [monitor]
