Unfortunately, it will not be possible since my actual hardware depends on kernel >= 4.6 :( Just now, I saw the problem again. For the first time, it happened twice in a small period. I was copying the e-mail from one IMAP server to my local HD. I use offlineimap, but this time it changed the backend to sqlite and started to create tons of database files, I think. My HDD IO stayed at 60/70% for a very long period. Hence, let's do a review of situations in which I saw the problem: 1) Local builds using `osc`; 2) During `zypper dup`; 3) When offlineimap created tons of database files; 4) During rsync-ing /home; 4) During usage of a virtual machine (the disk image was in an EXT4 partition). I think we can conclude that this problem is tightly coupled with actions that require a lot of writing to the HDD. Here is the specification of my HDD: hdparm -I /dev/sda /dev/sda: ATA device, with non-removable media Model Number: ST2000DM001-1CH164 Serial Number: W1E73CF5 Firmware Revision: HP34 Transport: Serial, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0 Standards: Used: unknown (minor revision code 0x001f) Supported: 9 8 7 6 5 Likely used: 9 Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 268435455 LBA48 user addressable sectors: 3907029168 Logical Sector size: 512 bytes Physical Sector size: 4096 bytes Logical Sector-0 offset: 0 bytes device size with M = 1024*1024: 1907729 MBytes device size with M = 1000*1000: 2000398 MBytes (2000 GB) cache/buffer size = unknown Form Factor: 3.5 inch Nominal Media Rotation Rate: 7200 Capabilities: LBA, IORDY(can be disabled) Queue depth: 32 Standby timer values: spec'd by Standard, no device specific minimum R/W multiple sector transfer: Max = 16 Current = ?
