Understanding BusyBox v1.30.1 Boot Issues on Kylin System

Analysis

This is the error message during system startup.

1. ACPI Related Errors

• “ACPI Error: Could not enable Globallock event (20190816/evxf evnt – 184)”
  • Hardware issue: There may be a malfunction or incompatibility with the hardware related to the global lock.
  • Software issue: There may be a defect in the ACPI driver or the ACPI implementation in the BIOS.
  • Meaning
    
    : ACPI (Advanced Configuration and Power Interface) could not enable the global lock (Globallock) event.
  • Possible Causes
    
    :
• “ACPI Error: No response from Global Lock hardware, disabling lock (20190816/euglock – 60)”
  • Hardware connection issue: The global lock hardware may not be properly connected to the motherboard.
  • Hardware failure: The global lock hardware may be damaged.
  • Meaning
    
    : ACPI did not receive a response from the global lock hardware, thus the lock was disabled.
  • Possible Causes
    
    :
• “ACPI: Failed to parse MCFG (- 19)”
  • Hardware configuration error: The system memory configuration may not match the configuration in the ACPI table.
  • ACPI table corruption: The ACPI table stored in the BIOS may be corrupted.
  • Meaning
    
    : ACPI could not parse MCFG (which may relate to memory configuration), error code – 19.
  • Possible Causes
    
    :

2. Loongson Related Messages

• “loongson generic_laptop: Not yet supported Loongson Generic Laptop/All – in – one detected!”
  • Lack of drivers: The current system lacks driver support for Loongson devices.
  • Operating system incompatibility: The operating system may not be compatible with Loongson architecture devices.
  • Meaning
    
    : A Loongson generic laptop/all-in-one has been detected, but the system does not currently support it.
  • Possible Causes
    
    :

3. BusyBox Related Information

• “BusyBox v1.30.1 (Kylin 1:1.30.1 – 4kylin6.1k1) built – in shell (ash)”
  • Meaning
    
    : The system is using BusyBox version 1.30.1, with the built-in ash shell.
  • Function
    
    : BusyBox is software that integrates many common UNIX tools, and ash is a simple shell.
• “Enter ‘help’ for a list of built – in commands.” and “(initramfs)”
  • Meaning
    
    : The user can enter ‘help’ to see a list of built-in commands, currently in the initial RAM filesystem (initramfs) environment.
  • Function
    
    : In this environment, users can try some basic system repair operations.

Solutions

1. ACPI Errors
   • Check hardware connections to ensure all hardware is correctly connected.
   • Update BIOS and ACPI drivers to the latest version.
   • If hardware failure is suspected, try replacing relevant hardware for testing.
2. Loongson Device Support Issues
   • Look for and install drivers and patches related to Loongson.
   • Contact the device manufacturer or Loongson official technical support for assistance.
3. Operations in BusyBox Environment
   • In (initramfs) state, you can try running filesystem check tools (like fsck, but proceed with caution) to check and repair filesystem errors.
   • Look for system log files (usually in the ‘/var/log’ directory) for more error clues to help locate and solve the issue.

Solutions

Terminal input:

bash exit

Repair the disk information /dev/nvme0n1p3 based on the above error prompt.

bash fsck -y /dev/nvme0n1p3

After the repair is complete, a message similar to ‘file system was Modified’ will appear.

3. At this point, enter exit to reboot.
