[SATA] status reports updated

[SATA] status reports updated

[Jeff Garzik]

My Linux SATA software/hardware status reports have just been updated. 
To see where libata (SATA) support stands for a particular piece of 
hardware, or a particular feature, go to

	http://linux.yyz.us/sata/

I've still got several patches from EMC (Brett) and IBM (Albert) to go 
through, as well as a few scattered ones from random authors.

I'm still working in BitKeeper for the time being.

Jeff:

You need to add a comment about the SATAII TX2/TX4 boards indicating
users have experienced data corruption with the sata_promise driver and
the SATAII TX4 board.

I've posted several emails to linux-ide about this.  Why haven't you
responded?

Promise TX2/TX4
Summary: No TCQ/NCQ. Full SATA control including hotplug and PM on all. 

[snip]

Update 2005/04/15: Support for the NCQ-capable SATAII TX2/TX4 boards was
recently added. NCQ support is waiting on libata core.

I've seen reports on the SX4, but not on the SATAII TX4.

URLs to messages you posted?

all pretty much the same report (by Joe).

which is somewhat more interesting, though rather fuzzy.  there's something 
about the driver deciding not to handle an interrupt (nobody cared), after 
which the driver is toast.  some claim that this might be dependent on which
disk is attached.

fundamentally, the problem is to isolate whether the (few) reported problems
are due to peculiarities of the reporting machines or not.

personally, I don't think this kind of warning is warranted.  it's like
saying that "rm" should have a warning because users have experienced 
data deletion when mistyping it...

Re: [SATA] status reports updated

[Joe Harvell]

I can understand the reluctance to put out a warning before verifying
the problem.

I would be willing to reproduce the problem if you have some debugging
data you want me to collect.

If you are concerned about the data corruption coming from the technique
I used (copying the OS installation from a utility boot environment),
then it may help you to know the following:

1. that I reproduced the problem 3 or 4 times with the 2.6 sata_promise
driver before deciding to try Promise's 2.4 driver; and 
2. that I used the same procedure of copying the same source OS from a
utility boot environment after switching to the 2.4 kernel and the
Promise driver, which resolved the problem.
