I just did a clean install of Solaris 10 on a Toshiba Satellite Pro 6100
laptop (the hard drive failed and was replaced.) The system is fully patched
as of yesterday and is generally working well.

SunOS xxx 5.10 Generic_125101-10 i86pc i386 i86pc

However, when it is rebooted the following entry now appears in the messages
file...

rootnex: [ID 561485 kern.warning] WARNING: ata: coding error detected, the
driver is using ddi_dma_attr(9S) incorrectly. There is a small risk of data
corruption in particular with large I/Os. The driver should be replaced with
a corrected version for proper system operation. To disable this warning,
add 'set rootnex:rootnex_bind_warn=0' to /etc/system(4).

Immediately prior to noticing this entry, I had set

atapi-cd-dma-enabled=1

and rebooted the system.

Should I worry about the message, or is it harmless?

Thanks,
