Bug#1136401: linux-image-6.12.86+deb13-amd64: SK Hynix BC501 NVMe causes ext4 remount-ro under I/O stress on ASUS ZenBook UX481FL
Package: linux-image-6.12.86+deb13-amd64 Version: 6.12.86-1 Severity: important Description: On an ASUS ZenBook UX481FL with dual boot (Windows 11 + Debian trixie), the ext4 root filesystem (nvme0n1p6) gets remounted read-only under heavy I/O stress (e.g. apt install, large downloads). Hardware: - SSD: SK Hynix BC501 HFM512GDJTNG-8310A, firmware 80001C00 - BIOS: UX481FL.308 - Dual boot with Windows 11 on the same NVMe (nvme0n1) Symptoms: - All /usr/bin commands fail with "Input/output error" - dmesg shows "orphan cleanup on readonly fs" on next boot - No explicit NVMe timeout errors in logs - Occurs reproducibly under apt/large file downloads Workarounds applied: - nvme_core.default_ps_max_latency_us=0 (partial improvement) - errors=continue,noatime in fstab - NVIDIA modules blacklisted The issue has been occurring repeatedly across multiple sessions.
