Developers merged the patch into Linux 7.1 on April 23, 2026. Gone are the I82092, I82365, and TCIC drivers. These handled PCMCIA host controllers from Intel PCI bridges, ISA buses, and Databook chips. The kernel shrank by 3,169 lines.
PCMCIA. Remember it? Those slim cards slotted into laptops for modems, Ethernet, WiFi. Peak popularity hit the late 1990s. By 2009, native support vanished from new machines. CardBus extended it briefly. Then USB swallowed the market.
Ethan Nelson-Moore led the charge. “PCMCIA is almost completely obsolete (the last computers supporting it natively were from ~2009),” he wrote in his commit message, as quoted by Phoronix. He noted no meaningful updates since 2022 discussions. The I82092 carried a null pointer bug from kernel 2.6.12 in 2005, patched only in 2021—on emulated hardware, not real gear.
ISA versions like I82365? Even dustier. No users left. Upstream Linux moves on.
Years of Pruning Dead Code
This isn’t sudden. Linux 6.4 started yanking PCMCIA char drivers. WiFi cards and CardBus-to-USB adapters followed. 2023’s commit 9b12f050c76f axed the core PCMCIA drivers. No reversals since.
But why now? Maintenance bites. AI tools and fuzzers flood maintainers with bogus bugs on unused code. Andrew Lunn’s patch series targets ISA and PCMCIA Ethernet drivers next—27,000 lines doomed. “Fixing these old drivers make little sense, if it is not clear they have users,” Lunn explained in his April 21 proposal, per LWN.net.
Phoronix detailed the trend: network drivers on the block due to AI noise. Tom’s Hardware echoed it, noting 3Com, AMD, SMSC relics from the 1900s. Developers waste hours triaging phantoms. No active hardware justifies the drag.
Fragment. Dead weight.
And it’s spreading. Linux 7.1 also drops Russia’s Baikal CPU drivers—efforts that fizzled. Intel 486 support phases out too. Linus Torvalds called it: “zero real reason” to prop up 37-year-old chips, as reported by Tom’s Hardware.
7.1’s Broader Cleanup Accelerates Modern Gains
Trims don’t dominate. Linux 7.1 packs punches elsewhere. A fresh NTFS driver lands—kernel-native, ditching FUSE slowness. Phoronix covers it here. Graphics surge: Intel and AMD lead updates. Intel QAT gets Zstd crypto boosts.
Scheduler tweaks favor workloads. High-res timers overhaul for precision. USB advances. Apple MacBooks gain SMC power tracking. Twelve new SoCs, ARM, RISC-V expansions.
So what? Lighter kernels boot faster, compile quicker. Fewer bugs lurk in shadows. Security scans ignore ghosts. Developers focus on 2026 hardware—AI accelerators, next-gen ARM servers, RISC-V clusters powering data centers.
Holdouts? LTS kernels like 6.1 or 6.6 keep legacy alive for years. Embedded niches might fork. But mainline marches forward. PCMCIA joins floppy drives, AGP, ISA buses in the archive.
No tears shed. Progress demands it.
X chatter confirms: Phoronix posted the news April 23, sparking nods from kernel watchers. Pirat_Nation highlighted AI-driven removals for ISA/PCMCIA nets. Consensus? Good riddance.
