redwood 6.12.96-Suvkernel test images (2026-10-31, random reboot fix)
=====================================================================

For: POCO X5 Pro 5G / Redmi Note 12 Pro 5G (redwood), running the AOSPA
Calcite 6.12 build of 2026-10-28 or later. redwood612-suvkernel-20261031-0033-rebootfix-vendor_boot.img
carries the ROM's vendor ramdisk, so use it only on such a build.

Flash from fastboot (back up your current boot, vendor_boot and dtbo
first):

  fastboot flash boot redwood612-suvkernel-20261031-0033-rebootfix-boot.img
  fastboot flash vendor_boot redwood612-suvkernel-20261031-0033-rebootfix-vendor_boot.img

  fastboot reboot

Fix in these images
-------------------
- Random reboot fix: the phone reset by itself every few minutes when
  left idle, almost always on a wall charger. The cause was in the
  hypervisor: on every wake-up from sleep, 6.12 re-fired interrupts
  that came in during sleep through the interrupt controller hardware,
  and when one was still being delivered the hypervisor crashed and
  reset the phone. Interrupts are now re-fired in software, as on the
  5.4 kernel.
- CPU deep sleep stays on, so standby battery life is unchanged.

Also in these images
--------------------
- 5 GHz Wi-Fi works and Wi-Fi uses the real MAC address
- Bluetooth audio offload (no video stutter over a BT headset)
- Battery driver on the current sysfs API

If it still reboots, send logs (USB debugging on, run on a PC right
after it comes back up):

  adb shell "mkdir -p /sdcard/logs; cd /sdcard/logs; dmesg > dmesg.txt 2>&1 || su -c dmesg > dmesg.txt; logcat -b all -d > logcat.txt; getprop persist.sys.boot.reason.history > bootreason.txt" && adb pull /sdcard/logs
