Good question -
Perhaps -mt patches will appear instead?

Right now I've fed all the stuff I feel makes sense to Linus for 2.4.15.
Once 2.4.15 is out I'll send some more bits to Marcelo, and also some bits
to Linus that are 2.5 material (eg PnPBIOS). The only "-ac" patch as such
would be for 32bit quota and other oddments so I don't think its worth the
effort.

Will this include the patches to allow for /proc/sys/vm/(min|max)-readahead
soon?

Thats pretty low on my priority list. Its actually not a hard patch to
extract although I'd prefer someone like Andrea who knows the new rather
undocumented VM did the merge
Hi,
2.4.13-ac will "flushing ide drives" on shutdown. This helped my laptop
from not '/dev/hdax no cleanly unmounted, checking' on startup. I'm sure
the system did not crash before that.
2.4.15-pre6 does not have this code and now sometimes some filesystems
seem not to be clean anymore on startup...
Will the ide_notify_reboot be included in 2.4.15 final?
-Marcel

You have a box with an IBM 20Gig 2.5" drive (just out of interest)

Probably not - the taskfile/LBA48 code wants more testing first. I believe
you can pick up the relevant patch from http://www.linux-ide.org however, thanks

Not exaclty. It is a 48Gig drive in a dell inspiron 8000. I think it is
IBM but the logs do not show a brandname. I can try open up the case tonight
if you want to know for sure?

'hdparm -i /dev/hdX' should tell you...

As I posted here last week, it's trivial to put the IDE drives into
standby mode just before powerdown instead. It has the same effect
and it would take just a few lines of code.
The Debian /sbin/halt does this now just before it asks the kernel
to poweroff, and it fixes this problem just fine. It would be better
if the kernel did it though.

It's an IBM IC25T048ATDA05-0 to be precise.

Thanks. It seems IBM laptop drives are the ones that specifically need this
fix. That ties in with the windows 98 reports/microsoft fixes.

I have Debian bugreports saying that it's not only IBM laptop drives.
It happens on Seagate, Samsung, Maxtor as well.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=110804&repeatmerged=yes
Note that the final fix (putting the drives in standby mode) is not
discussed in this bug report - I experimented first with turning off
the write cache in the shutdown scripts which kind of worked but
feels not quite right - you might need just enough write activity
after that to completely flush the on-disk cache.

Would that be enough reason to add only the specific flushing code of
the taskfile patch (if at all possible) to the kernel? Maybe Andre is
willing to extract the relevant code in a seperate patch...

If it will go into mainstream, please change it to config option or
something like that. I'm doing
for a in /dev/hd[a-z]; do hdparm -Y $a; done
in my poweroff script. With -ac /sbin/halt then stops on each disk
for couple of seconds, because of drive in sleep mode does not respond,
and so IDE driver has to timeout, reinit interface and flush cache
(fortunately drive does not spin up again).

This also affects my Desktop PC with two IBM Deskstar 60GXP 40GB drives. I'd
like to see it in 2.4.15.

I'm using IBM 240Z with IBM-DJSA-220 (20GB, 9.5mm thickness) with
2.4.15-pre7 and it does not need any fixes. Disk clean after shutdown.

Does it have write caching enabled? check with hdparm ( I think you need one of
the latest hdparm versions...)

Exact. But noone reports the 'IBM' part, not even hdparm -i...
But hdparm does shows that writecaching is enabled.

I've got one of those.. IBM Thinkpad T22 running on Linux Redhat 7.2
and Kernel 2.4.9-13. And I haven't really been stumbeling into any such
problems lately.. could try to upgrade to 2.4.14 and see if it's still
stable ;)

Thats somewhat undefined in its behaviour. You might also page after the
hdparm -Y

for a in /dev/hd[a-z]; do /sbin/hdparm -Y $a; done
/bin/sleep 1
/sbin/halt -d -f -i -p -h
works without a glitch - libc & co. is already in memory due to running
other code, hdparm is read during first pass through the loop, and cat
brings /sbin/halt into the memory. And as root filesystem is mounted
read-only at that time, there are of course no atime updates pending from
these accesses.
