usb: quirks: Add NO_LPM quirk for SanDisk Extreme 55AE
JIRA: https://issues.redhat.com/browse/RHEL-116016 commit 19f7955 Author: Jiayi Li <lijiayi@kylinos.cn> Date: Thu, 8 May 2025 13:59:47 +0800 This device exhibits I/O errors during file transfers due to unstable link power management (LPM) behavior. The kernel logs show repeated warm resets and eventual disconnection when LPM is enabled: [ 3467.810740] hub 2-0:1.0: state 7 ports 6 chg 0000 evt 0020 [ 3467.810740] usb usb2-port5: do warm reset [ 3467.866444] usb usb2-port5: not warm reset yet, waiting 50ms [ 3467.907407] sd 0:0:0:0: [sda] tag#12 sense submit err -19 [ 3467.994423] usb usb2-port5: status 02c0, change 0001, 10.0 Gb/s [ 3467.994453] usb 2-5: USB disconnect, device number 4 The error -19 (ENODEV) occurs when the device disappears during write operations. Adding USB_QUIRK_NO_LPM disables link power management for this specific device, resolving the stability issues.
