Linux Drops Support For 486 and Early Pentium Processors

Slashdot

An anonymous reader quotes a report from ZDNet: RIP, 486 processor. You've had a long run since Intel released you back in 1989. While Microsoft stopped supporting you with the release of Windows XP in 2001, Linux kept you alive and well for another 20+ years. But all good things must come to an end, and with the forthcoming release of the Linux 6.15 kernel, the 486 and the first Pentium processors will be sunsetted. Why? Linus Torvalds wrote recently on the Linux Kernel Mailing List (LKML), "I really get the feeling that it's time to leave i486 support behind. There's zero real reason for anybody to waste one second of development effort on this kind of issue." Senior Linux kernel developer Ingo Molnar put Torvalds' remark into context, writing, "In the x86 architecture, we have various complicated hardware emulation facilities on x86-32 to support ancient 32-bit CPUs that very very few people are using with modern kernels. This compatibility glue is sometimes even causing problems that people spend time to resolve, which time could be spent on other things." "This will be the first time Linux has dropped support for a major chip family since 2012, when Linux stopped supporting the 386 family," notes ZDNet's Steven Vaughan-Nichols. "Moving forward, the minimum supported x86 CPU will now be the original Pentium (P5) or newer, requiring the presence of the Time Stamp Counter (TSC) and the CMPXCHG8B (CX8) instruction. These features are absent in the older 486 and early 586 processors, such as the IDT WinChip and AMD Elan families." That said, you can continue running Linux on Pentium CPUs, but you'll have to "run museum kernels," as Torvalds pointed out in 2022 when he first floated the idea of ending support for 486.

Delta Air Lines Class Action Cleared For Takeoff Over CrowdStrike Chaos

A federal judge has allowed key parts of a class action lawsuit against Delta Air Lines to proceed, stemming from massive flight disruptions caused by CrowdStrike's faulty Windows update in July 2024. The Register reports: Delta blamed its reliance on Microsoft software and the CrowdStrike incident for its woes. However, according to the plaintiffs in the action (PDF), both companies offered the airline assistance, which Delta turned down. Customers of the Atlanta-based carrier affected by the delays and cancellations claim they struggled to secure refunds and compensation from the airline. The plaintiffs allege that "although Delta offered reimbursement of eligible expenses through their website and app, Delta failed to clarify that the customer would only be receiving a partial reimbursement." "Furthermore, Delta did not disclose to its customers that acceptance of the partial reimbursement would release any legal claims the customer may have against Delta until after the customer 'click[ed] on the button to accept the partial reimbursement.'" The action concerns both US domestic and international travel. The former is covered by US Department of Transportation rules, which require airline agents to "inform customers of their right to a refund ... before making an offer for alternative transportation, travel credits, vouchers, or other compensation in lieu of refunds." The latter claims come under the Montreal Convention, which is designed to be a single, universal treaty to govern airline liability. Delta, which estimated its operational losses at around half a billion dollars due to the outage, sought to dismiss the complaint. While the US District Judge, Mark H. Cohen, granted the airline's motion to dismiss some of the claims, he permitted others to proceed. These were Count I (breach of contract based on failure to refund) and Count XII (violation of the Montreal Convention).
