I have seen this error message on all versions of kernel 2.6 since the
beginning and also on kernel 2.4 and asked about this error message some
time ago, but didn't get an answer.
It happens on heavy random access (heavy headmovement) on disk but also
on fsck(.ext3). Since kernel 2.16 or 2.6.17 (since printing "Info
fld=xxxxxx) this error message is getting rare.
P.S. I've never seen any data corruption, so this is not a serious error
for me , but might be for others.
Is this only limited to sata_promise or are there also other sata/pata drivers
that have this type of error message?
There has to be a reason for this message. Is the controller/disk telling the
kernel "stop pushing me or i will loose data"?
I don't know, if there are other drivers, cause for my pata drives I use
the "old" ide via82cxxx driver not libata pata and there I don't get any
error messages of this type.
And is there realy _no_ data corruption? This fileserver should store my
picture archive and i don't/can't do every day/week backups. And as long as i get
this message i don't trust this machine/controller/disk/kernel/driver/whatever.
I have seen no really no data corruption, not even under heavy load and
I am using the SATAII150 TX4 (I think the driver makes no difference
between your and my controller except the the transfer rate) controller
about a year without any problems on my productions system.
I guess this error, means something like "timeout on last command, tryed
again with success" or similar.
I hope any of the driver programmers will soon, get on this (I'm still
waiting for ATAPI support on this driver, cause I extra bought a SATA
dvdwriter to be ready for future).
