Subject: WRITE SAME failed in recent kernels

Dear All,

In the setting of an SSD and an HDD connected to a HighPoint RocketRAID
620, I am seeing quite a number of log messages such as:

Apr 14 06:02:30 jekaterina kernel: [  952.460537] sd 8:0:1:0: [sde]
Unhandled error code
Apr 14 06:02:30 jekaterina kernel: [  952.460542] sd 8:0:1:0: [sde]

Apr 14 06:02:30 jekaterina kernel: [  952.460557] end_request: I/O
error, dev sde, sector 2831612792
Apr 14 06:02:30 jekaterina kernel: [  952.460566] sde1: WRITE SAME
failed. Manually zeroing.

with sde being the regular HDD.

Now, I am aware that the HighPoint driver, rr62x, isn't part of
mainline, and thus I have contacted HighPoint Technologies as well, but
I would like to know how to ascertain whether this is, indeed, a problem
with their driver, or if it's a problem pertaining to the kernel itself.

Any help, really, is much appreciated, even if it amounts to "HighPoint
is to blame", as I would then have that on higher authority than myself.

Best regards,

Sune Mølgaard
