From: Niklas Cassel Date: Tue, 20 Jan 2026 10:32:38 +0000 (+0100) Subject: ata: libata-core: Quirk INTEL SSDSC2KG480G8 max_sectors X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5f64ae1ef639a2bab7e39497c55f76cc0682f108;p=thirdparty%2Fkernel%2Flinux.git ata: libata-core: Quirk INTEL SSDSC2KG480G8 max_sectors Commit 9b8b84879d4a ("block: Increase BLK_DEF_MAX_SECTORS_CAP") increased the default max_sectors_kb from 1280 KiB to 4096 KiB. INTEL SSDSC2KG480G8 with FW rev XCV10120 times out when sending I/Os of size 4096 KiB. Enable ATA_QUIRK_MAX_SEC, with value 8191 (sectors) for this device, since any I/O with more sectors than that lead to I/O timeouts. With this, the INTEL SSDSC2KG480G8 is usable again.
