Good morning, this is Linux Kernel Daily for March 21st, 2026.
Today we're covering 19 commits focused on stability fixes for the 7.0 release candidate. The largest update comes from Linus Torvalds merging Dave Airlie's DRM fixes tag, addressing critical graphics driver issues. This includes 40 commits fixing screen corruption on ThinkPad P14s displays, memory leaks in AMD and…
Torvalds also merged Greg Kroah-Hartman's TTY and serial driver fixes, resolving several 8250 UART driver problems including a TX deadlock when using DMA and interrupt storm issues with DesignWare UARTs. The update includes a fix for infinite loops in the serial core that could affect PORT_UNKNOWN devices.
Additional merges include Mark Brown's SPI fixes addressing race conditions and DMA ordering problems in Qualcomm's GENI driver, and Miquel Raynal's MTD updates fixing SPI NOR capability checks and NAND controller timing issues.
Joerg Roedel contributed IOMMU security fixes, including patches to prevent identity domain usage when AMD's SNP is active and fixes for Intel VT-d hardlockups during TLB synchronization.
The Hyper-V subsystem received ARM64 MSHV support improvements and memory handling fixes from…
