(probe30:iir0:2:0:0): inquiry data fails comparison at DV1 step

[Julien Cigar-2]

Hello,

I'm using FreeBSD 7.0 with an Intel SRCZCR
(http://support.intel.com/support/motherboards/server/srczcr/) RAID
controller. The machine is configured as the following:
- RAID 1 + one spare disk where the system is installed
- RAID 5 + one spare disk mounted under /usr

The disks are from Seagate (146 GB, U320).
It seems to work fine (it's a fresh install) except that I have this
message on boot :

(probe30:iir0:2:0:0): inquiry data fails comparison at DV1 step

Should I worry or can I ignore this message ? What's the exact meaning
of it ?
The complete dmesg output can be found on
http://rafb.net/p/4AWejC78.html

In advance thanks,
Julien

ps: could you reply on my email address as I'm not subscribed on this
ML.

There's a mysterious problem here that looks like it's some sort
of use-after-free or data corruption.  I've seen similar reports
but haven't been able to debug it.  However, it seems to be harmless.

Oops, my apologies, so many drivers, so little brainpower.  This problem
may have been fixed back in January, but only in 8-CURRENT.  I'll look
into merging the fix into FreeBSD 7.

  Any chance to see this fix in upcoming release? We also have the same problem:

  6.6 MB/s is too slow these days :(( Working good with 6.x, damaged in 7.x
