Re: [smartmontools-support] Kernel errors on Solaris 11 x64 after moving from 5.39 to 5.40

Christian,

It appears after this one:

=== START OF READ SMART DATA SECTION ===

REPORT-IOCTL: Device=/dev/rdsk/c12t0d0p0 Command=SMART STATUS CHECK

Both versions behave as expected, sent identical commands and got identical replies from the disk.

The only difference is that 5.39 sends SMART RETURN STATUS earlier and twice, first without request for sense data (ATA output registers):

IDENTIFY DEVICE
SMART RETURN STATUS (SAT CK_COND=0) <== 5.39 SMART RETURN STATUS (SAT CK_COND=1) <== 5.39 SMART READ ATTRIBUTES SMART READ THRESHOLDS SMART RETURN STATUS (SAT CK_COND=1) <== 5.40

For further diagnostics we need to know which command produces the warning. Unfortunately the syslog entry does only print the SAT command code which is the same for all commands.

If possible please apply the attached patch to 5.40 (or current SVN) and repeat the test. After which command does the warning appear in the syslog?

Thanks,
Christian
