However, during system\nsuspension with connected USB devices, multiple power-down requests for\nthe UTMI pad result in a mismatch in the reference count, which in turn\nproduces warnings such as:\n\n[ 237.762967] WARNING: CPU: 10 PID: 1618 at tegra186_utmi_pad_power_down+0x160/0x170\n[ 237.763103] Call trace:\n[ 237.763104] tegra186_utmi_pad_power_down+0x160/0x170\n[ 237.763107] tegra186_utmi_phy_power_off+0x10/0x30\n[ 237.763110] phy_power_off+0x48/0x100\n[ 237.763113] tegra_xusb_enter_elpg+0x204/0x500\n[ 237.763119] tegra_xusb_suspend+0x48/0x140\n[ 237.763122] platform_pm_suspend+0x2c/0xb0\n[ 237.763125] dpm_run_callback.isra.0+0x20/0xa0\n[ 237.763127] __device_suspend+0x118/0x330\n[ 237.763129] dpm_suspend+0x10c/0x1f0\n[ 237.763130] dpm_suspend_start+0x88/0xb0\n[ 237.763132] suspend_devices_and_enter+0x120/0x500\n[ 237.763135] pm_suspend+0x1ec/0x270\n\nThe root cause was traced back to the dynamic power-down changes\nintroduced in commit a30951d31b25 (\"xhci: tegra: USB2 pad power controls\"),\nwhere the UTMI pad was being powered down without verifying its current\nstate. This unbalanced behavior led to discrepancies in the reference\ncount.\n\nTo rectify this issue, this patch replaces the single reference counter\nwith a bitmask, renamed to utmi_pad_enabled. Each bit in the mask\ncorresponds to one of the four USB2 PHYs, allowing us to track each pad's\nenablement status individually.\n\nWith this change:\n - The bias pad is powered on only when the mask is clear.\n - Each UTMI pad is powered on or down based on its corresponding bit\n in the mask, preventing redundant operations.\n - The overall power state of the shared bias pad is maintained\n correctly during suspend/resume cycles.\n\nThe mutex used to prevent race conditions during UTMI pad enable/disable\noperations has been moved from the tegra186_utmi_bias_pad_power_on/off\nfunctions to the parent functions tegra186_utmi_pad_power_on/down. This\nchange ensures that there are no race conditions when updating the bitmask." affected: [{"versions":[{"version":"a30951d31b250bf3479c00e93646b6cc6fb42a56","status":"affected","versionType":"git","lessThan":"ba25131b3c1ceec303839b2462586d7673788197"},{"version":"a30951d31b250bf3479c00e93646b6cc6fb42a56","status":"affected","versionType":"git","lessThan":"1db527f0cb8f677adadd4e28e5bc77aaf5d4e4c9"},{"version":"a30951d31b250bf3479c00e93646b6cc6fb42a56","status":"affected","versionType":"git","lessThan":"628bec9ed68a2204184fc8230a2609075b08666e"},{"version":"a30951d31b250bf3479c00e93646b6cc6fb42a56","status":"affected","versionType":"git","lessThan":"b47158fb42959c417ff2662075c0d46fb783d5d1"}],"vendor":"Linux","product":"Linux","defaultStatus":"unaffected"},{"versions":[{"version":"6.3","status":"affected"},{"version":"0","status":"unaffected","versionType":"semver","lessThan":"6.3"},{"version":"6.6.92","status":"unaffected","versionType":"semver","lessThanOrEqual":"6.6.*"},{"version":"6.12.30","status":"unaffected","versionType":"semver","lessThanOrEqual":"6.12.*"},{"version":"6.14.8","status":"unaffected","versionType":"semver","lessThanOrEqual":"6.14.*"},{"version":"6.15","status":"unaffected","versionType":"original_commit_for_fix","lessThanOrEqual":"*"}],"vendor":"Linux","product":"Linux","defaultStatus":"affected"}] ## Licenças e atribuição das fontes CISA Known Exploited Vulnerabilities: https://www.cisa.gov/known-exploited-vulnerabilities-catalog (US government work) GitHub Advisory Database: https://github.com/advisories (CC BY 4.0) Have I Been Pwned: https://haveibeenpwned.com/ (CC BY 4.0) CVE Program (CVE records): https://www.cve.org/Legal/TermsOfUse (CVE Terms of Use) Copyright © 1999-2026, The MITRE Corporation.
