The trampoline code is written while secondary\nCPUs are powered on (at least that true for RK3188 CPU).\nSometimes that leads to kernel hang. Probably because secondary\nCPU execute trampoline code while kernel doesn't expect.\n\nThe patch moves SRAM initialization step to the point where all\nsecondary CPUs are powered down.\n\nThat fixes rarely hangs on RK3188:\n[    0.091568] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000\n[    0.091996] rockchip_smp_prepare_cpus: ncores 4","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/0223a3683d502b7e5eb2eb4ad7e97363fa88d531","https://git.kernel.org/stable/c/1eb67589a7e091b1e5108aab72fddbf4dc69af2c","https://git.kernel.org/stable/c/265583266d93db4ff83d088819b1f63fdf0131db","https://git.kernel.org/stable/c/3c6bf7a324b8995b9c7d790c8d2abf0668f51551","https://git.kernel.org/stable/c/47769dab9073a73e127aa0bfd0ba4c51eaccdc33"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2025-39752","score":0.00176,"percentile":0.07037,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
