Hi -- Please help me diagnose and fix this problem. My five month old Dell laptop with updated firmware and new up-to-date Buster completely hangs and requires a hard reboot after 7-40 days uptime. While reading something onscreen or away from the laptop, the system hangs completely: screen freezes, keyboard is unresponsive, lid close fails to sleep, can't ssh in, pings fail. Hard reboot is required.
Actions taken: - re-installed Buster twice over several months - ran fsck.ext4 -y /dev/sda2 when fsck failed on boot - ran bad blocks - run smartmontools long test weekly; no errors reported in logs. Sometimes there are errors in syslog like this before a crash: > Apr 2 06:04:18 spike3 kernel: [539637.882916] EXT4-fs error (device sda2): > ext4_lookup:1590: inode #55838123: comm updatedb.mlocat: iget: checksum > invalid Today there were no syslog errors for weeks before the system hung. After rebooting, errors like these appeared: > Apr 20 16:05:57 spike3 kernel: [ 887.007328] EXT4-fs error (device sda2): > ext4_lookup:1590: inode #55842004: comm GMPThread: iget: checksum invalid > Apr 20 16:08:53 spike3 kernel: [ 1062.821504] EXT4-fs error (device sda2): > ext4_lookup:1590: inode #55842002: comm DOM Worker: iget: checksum invalid Any ideas? Thanks in advance! Ralph
