KERNEL RC7 PLUGS FUTEX RACE AND MCE BUG; OMARCHY FIXES UPGRADE TRAP

By RepoJournal · Filed · About Linux

Linus merged five critical subsystem fixes overnight, including a futex race that can leave tasks stuck and a Quattro upgrade script that silently fails mid-transition, leaving the system in an unsafe state.

The kernel is tightening up for 7.2 final. A race in futex_pivot_pending() during private hash resize can cause stuck tasks [1], while an MCE CMCI discovery initialization ordering bug required setting up the polling timer first [2]. Greg KH's char-misc and tty/serial/USB trees landed documentation updates and device quirks [3] [4] [5], all standard RC7 fare. Meanwhile, omarchy faces more urgent ground-level pain. The Quattro upgrade script aborts silently two-thirds through when bin/omarchy-done is missing, leaving NetworkManager enabled while iwd remains active, and nothing printed to signal failure [6]. The About window also couldn't fit its content in the default 875x600 float, causing lines to wrap over the logo [7]. Both issues shipped fixes in the latest PRs [8] [9] [10], with test harness improvements to catch these failures earlier by running the full suite instead of stopping at first failure.
