This report outlines a critical bug found in Magisk v28.0 that causes bootloops on Redmi 6 and 6A devices running Android 11.

The specific commit, b38fd1ca5f15ed22858c7737879c38d360e78eac, introduced the issue. Canary builds 27006 and 27007 boot successfully, while subsequent canary and beta builds (27008, 28001, 28000) lead to crashes during the init process.

**Crash Symptoms**

The console output reveals an error related to the `/proc/mounts` file and the inability to mount the `/` filesystem. This results in the system failing to initialize and rebooting to the bootloader.

**Troubleshooting**

Reverted Magisk builds without the problematic commit function correctly on the affected devices. This strongly indicates that commit b38fd1ca5f15ed22858c7737879c38d360e78eac is the root cause of the issue.

**Details**

- Device: Redmi 6/6A
- Android version: 11
- Magisk version name: Magisk v28.0
- Magisk version code: 28001

**Recommendation**

It is strongly advised to avoid installing Magisk v28.0 on Redmi 6/6A devices until this bug is addressed in a future update. Users experiencing this issue should rollback to a previous Magisk version or build versions without the problematic commit. This issue is likely to affect other devices as well, so further investigation and testing are required to determine the full scope of the problem.
