From: Edson Juliano Drosdeck Date: Thu, 26 Jun 2025 11:24:42 +0000 (-0300) Subject: mmc: sdhci-pci: Quirk for broken command queuing on Intel GLK-based Positivo models X-Git-Tag: v6.6.100~76 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7ac120c00c5acd9a4105aa778ee9333f95fe0dbb;p=thirdparty%2Fkernel%2Fstable.git mmc: sdhci-pci: Quirk for broken command queuing on Intel GLK-based Positivo models commit 50c78f398e92fafa1cbba3469c95fe04b2e4206d upstream. Disable command queuing on Intel GLK-based Positivo models. Without this quirk, CQE (Command Queuing Engine) causes instability or I/O errors during operation. Disabling it ensures stable operation on affected devices.
