Hello all,
I've taking email addresses from the last NCQ blacklist changes going
into the kernel.
This Fujitsu drive also gives me spurious command completions. Detailed
output also available at https://bugzilla.redhat.com/show_bug.cgi?id=366181.
Let me know if you need more info or anything else.
regards,
Florian La Roche

Thanks. We're currently trying to find out what's actually going on
with all these drives. At first, drives which got blacklisted aren't
many and made sense (had other problems with NCQ, etc..) but with new
generation drives from many vendors showing the same symptom, we aren't
too sure now.
I'll keep your email in my todo list and add the drive to the blacklist
once the problem is verified.
Thanks.

Is there a way to tell whether Windows is using NCQ or not? I checked
the system log (or whatever it's called) on my notebook and is clean
but I'm not sure it's using NCQ (I don't even know if it'd log
spurious completions somewhere).

Something new on the NCQ front?
Just asking if you need someone to test some of your ideas?
I got the "WDC WD740ADFD-00NLR1"
by the way, and OT, did the Plextor DVD-RW drive reach you, Tejun?

I now have affected drives on my desk and am gonna try reproduce it. My
gut feeling says it's timing related problem on controller / driver
side. Please wait a bit.
> by the way, and OT, did the Plextor DVD-RW drive reach you, Tejun?
No, not yet. Do you have a tracking number or something?
Thanks.

Okay, no problem, I am just curious.

No, I havn't... all I got is the bill... but that doesn't help because
we choosed to use shipment without enshurance... there is no tracking
number. Mhhh that sucks... i can't get rid of the bad feeling that it
got lost. But I'll try to make some checks.

Hi!
Just using kernel 2.6.24-rc2 (325d22df7b19e0116aff3391d3a03f73d0634ded).
When booting the system hangs, using the emergency-sync a couple of times gets
the system to go on at some point.
Its always around starting X/Firewall (can't actually say whats done in this
moment).
Looking at dmesg i found this (NCQ disabled ...)
dmesg output

So is this problem (which in another email you attributed to smartd) also
present in 2.6.23?
And is is still present in 2.6.24-rc3?
