Latest working kernel version:
Earliest failing kernel version:
Distribution: Gentoo
Hardware Environment: IDE interface: Intel Corporation 82801DB (ICH4) IDE Controller (rev 02)
Software Environment: smartmontools-5.36
Problem Description:

When smartd starts and initializes device parameters, HSM violation errors are reported. The smartd is configured in the following way:

/dev/sda -d ata -a -o on -R 194 -m root -M daily
(the same parameters for sdb).

When smartd starts, the following is reported to the syslog:
