Ubuntu启动崩溃并出现release_bts_buffer调用栈问题求助

Hey there, I’ve run into a few similar cases where Ubuntu laptops throw a boot crash with the release_bts_buffer call stack—especially when the issue isn’t linked to recent system updates or software installs. Let’s walk through some practical steps you can try before committing to a reinstall, plus useful tips if you do end up needing to wipe and start fresh.

First, Try These Non-Reinstall Fixes #

• Start with hardware checks: Since this isn’t tied to a software change, faulty RAM or storage is a frequent culprit here. Boot into a Ubuntu live USB (the same kind you used for initial installation), then run these tools:
  • Launch memtest86+ from the live boot menu to scan for RAM errors—let it run for at least one full pass to catch issues
  • Run smartctl -a /dev/sda (replace /dev/sda with your actual drive identifier, like /dev/nvme0n1 for NVMe SSDs) to check for SSD/HDD health problems
• Boot into recovery mode: Reboot your laptop, hold Shift (or Esc on newer UEFI systems) to bring up the GRUB menu. Select "Advanced options for Ubuntu" > "Recovery mode", then try these options in order:
  • fsck: This scans and fixes filesystem errors on your main drive—this often resolves boot crashes caused by corrupted system files
  • dpkg: Repairs broken package installations (even if you didn’t install new software, cached packages can sometimes get corrupted)
  • Root shell prompt: If recovery mode loads successfully, try updating your initramfs with update-initramfs -u—this fixes issues with the initial boot filesystem image
• Temporarily disable the BTS module: If the crash happens right after selecting Ubuntu in GRUB, you can test if the BTS module is the problem. Press 'e' to edit the boot line, find the line starting with linux, add module_blacklist=bts at the end, then press Ctrl+X to boot. If this works, make the change permanent by editing /etc/modprobe.d/blacklist.conf and adding blacklist bts

If You Decide to Reinstall #

• Back up your data first—no exceptions: Use the live USB to mount your existing Ubuntu partition and copy all critical files (Documents, Pictures, config folders, etc.) to an external drive. It’s easy to overlook important files, so double-check before proceeding
• Use a fresh, verified ISO: Download the latest stable Ubuntu ISO, verify its checksum to ensure it’s not corrupted, then create a new live USB (avoid reusing an old one that might have hidden errors)
• Opt for a partial reinstall if possible: If you set up separate partitions for / (system) and /home (user files) during your initial install, select "Something else" in the installation wizard. Format the / partition but leave /home untouched—this way you’ll keep all your user files, settings, and installed apps without having to restore everything manually
