Greetings Matthew,

Thanks for the feedback, but lkml needs it or it will not be adopted.
I know the driver is stable and effectively perfect in operations.
So I do not understand the total ignore I receive about it.

respectfully

Andre's ide.2.4.16.12102001.patch works great here. I strongly recommend
it be considered for 2.5 if not also for 2.4.

the -ac tree had the patch in until at least 2.4.13-ac,
which I run on my laptop because it is the latest kernel
that flushes the ide-drive writecache at shutdown.
Before that I had regular filesystem corruptions...

For certain laptops with IBM 2.5" drives its basically
mandatory. Any laptops that needed the Win98 update (or were shipped with
the win98 update) for this.

Current sysvinit/initscripts has a sort of unreliable workaround for this,
which doesn't always help.

Cyrix486/66 Slackware 8.0 12Megs Ram works great with 
linux 2.4.16 + ide + rml-preemptible_patch.
hard drive is Seagate 6.4Gb 
I have used this combination before and no
problems at all.

I wish it were an easy 2.4 one - its the first thing that fixed my HPT370 DMA 
timeouts too.

Just to avoid overperfectness... ;))

Has anyone succeeded in fixing the sis5513 driver to work with ATA100 chips?
I get heavy disk corruption with SiS730S chipset mobo (ASUS A7S-VM).

I'm on it. Had some intermittent successes and thought to have a correct 
patch until today (one 2002 week with ATA100)...
But I had a bugreport today and same dma problems on my machine after a 
BIOS flashing and a new drive in the system.
Currently in heavy debugging.

PB: chip seems to init itself correctly on extended periods of time on 
my config! Makes testing rather difficult :-(

For example, with the *exact* same code this evening I had:
- a system freeze just after /sbin/init load,
- a crash after ext3 fs errors before init,
- a somewhat working boot (some weird library errors caused "ip" to not 
work),
- a fully functionnal system (no error reported, some file copies, 
reboot with ide=nodma, e2fsck -f -> no error).

If you have a system you can test on without fear of breaking things 
I'll send you patches as soon as they'll work again on my config.
Better if you want to proof-read the code :

Debugging ended. Patch cleaned from debugging code submitted to Andre.
After numerous bug reports and google search I understood that the 
problem is an *hardware* one on my board.

Should have been 100% sure this was an hardware pb at this time. Non 
deterministic behaviour in my code could not have had any other source.

People encountering problems using SIS chipsets should try the driver 
available here:

I also vote for inclusion in 2.4. It runs on several workstations and
a file-server using Software RAID-5 on 3 IBM IDE disk running EXT3
(formerly ReiserFS - but it's speed sucks on RAID5 IDE devices ??) -
no problems!

I spent a couple of hours beating the crap out of it,
and none actually came out.  I'd vote for prompt inclusion
in 2.5, and inclusion in 2.4.x-pre1 when it's shown to be
stable.

I vote for doing the reverse. The 2.4 codebase is the more tested, the 2.5
is a forward-port. Given all the related block changes still settling out
in 2.5, changing IDE might make block layer/IDE issues hard to sort out.
Let's see it in the next 2.4.x-pre1.
