[PATCHSET] Linux 2.4.19-pre7-jam1

[PATCHSET] Linux 2.4.19-pre7-jam1

[J.A. Magallon]

Hi.

New version, just collected latest important bugfixes:

- Serial port number assign (05-serial.gz)
- pagemap.h include for fs/ (04-fs-pagemap.gz)
- unlocking order in buffer.c::end_buffer_io_kiobuf (03-unlock-bh-before.gz)

And a couple new additions:

- ide update -3a (very shrinked wrt original, the big ppc part has gone
  in mainline)
- netconsole-C2-2 (for my beowulf...)

Rest as usual, O1-sched-k3 (is any backport of the updates planned ??)
mini-low-lat, splitted-vm-33, bproc-3.1.9.

Enjoy !!

There is a micro bug in 3a, look for 4 to arrive.

Can it be related to my system getting hung on boot trying to do
an hdparm ?
I had not the time to dig more, just disabled it and booted fine (I had
some work to get done...)

TIA

Yep

That is the bug on the ide_driveid_update call.
Find it and change the #if 1 to #if 0

Yep, here it is exactly the same.

I also changed '#if 1' to '#if 0' as Andre mentioned but it has no effect,
my machine hangs at boot time....

Thanks for the positive feedback!
About to add and test HPT372 final and then complete the MMIO operations.
Next will be to make the driver do the error recovery path that block does
not support and accellerate IO with true zero-copy.  Lastly will make the
entire stack modular, which is about 50% completed.

FYI, I have tried it as well (ide-2.4.19-p6.all.convert.3a.patch
on 2.4.19-p7 plus your recommended #if 0 change) and it has been
working nicely for me as well on a number of machines.  This
certainly seems to be a nice improvement.

Can you go into a little detail on your plans for error handling?

I think the currently error handling for the ide-subsystem,
especially in the presence of sequences of bad sectors, is not
especially robust (and is quite slow)...  In one case I tested
yesterday (with 2.4.19-p7 plus your patch) using a 340 MB
microdrive with a big chunk of bad sectors on it (the device
admittedly is in pretty sorry shape but makes an excellent
ide-subsystem tester ;-), the kernel wedged solid while trying to
read from it...

Well the proper solution is for me to finish the "ide-flash" subdriver.
As CFA devices have special error transformations and decodes, as will any
SDA device.

Proper error path in the driver ... hmmm, I have a discription and batted
it around and more people understand the problem now.  The issue becomes
in full disclosure and not producing a mass panic.  I would like to have a
solution complete before "wolf" and nothing to kill the beast in sight.

I just merged "ide-2.4.19-p7.all.convert.5.patch" into my tree, and now
it works also for me. With former versions my machine hung at boot time,
wether #if 0 or 1 was set.

Just a 'me too'. Patch -5 booted fine, I have put a -jam2 in the usual place:

Boots fine here. I'll bang on the ide-scsi bit by burning some stuff.
