Package: laptop-mode-tools Version: 1.72-1 Severity: critical Justification: breaks the whole system
Dear Maintainer, just to note, my hardware is Dell e7450, disk drive is: ata2.00: ATA-9: SAMSUNG SSD PM851 mSATA 256GB, EXT4AD0Q, max UDMA/133 * What led up to the situation? `apt full-upgrade -V` done on Feb 3, causing `laptop-mode-tools` update to version `1.72-1` * What was the outcome of this action? After disconnecting laptop from power source (docking station) system become irresponsive - seemed like disk failure. I have quickly done full disk backup (using Clonezilla, on AC, without any errors) and started looking for cause. Dell Onboard Diagnostics software found no problems with my hard drive (running long DST) Trying to reproduce this issue on some random gparted usb stick I had on my desk failed - so this definitely meant software problem in my Debian. Finally, looking into what updated recently I have found that laptop-mode-tools has been updated yesterday. I've purged the package, rebooted and system become stable without AC again. Further tests narrowed case to (at least one of) two modules: * intel-hda-powersave.conf * intel-sata-powermgmt.conf Setting: CONTROL_INTEL_HDA_POWER=0 CONTROL_INTEL_SATA_POWER= made laptop-mode-tools usable again. (see attached modified config files) * Logs With laptop-mode-tools in standard configuration, when disconnected from AC I was getting in `dmesg` similiard messages every few seconds: [ +3.568871] sd 1:0:0:0: [sda] Synchronizing SCSI cache [ +0.005399] sd 1:0:0:0: [sda] Stopping disk [ +1.222534] sd 1:0:0:0: [sda] Starting disk [ +0.347509] EXT4-fs (dm-3): re-mounted. Opts: data=ordered,commit=600 [ +0.261822] EXT4-fs (dm-1): re-mounted. Opts: data=ordered,commit=600 causing `sda` to be completely unusbable, causing `dm_crypt` errors in the end: Feb 04 00:27:52 odyssey kernel: INFO: task dmcrypt_write:247 blocked for more than 120 seconds.
