I have a question!!
I did setting SMP in Linux OS..
Linux version is 2.2.5...
By the way, error is happened....
Error is the contents about SCSI...
And, sometimes, computer is downed...
Why did this error happen?
Possibly, which patch is needed??
Please, give me an answer!!
p.s. Possibly, if there is a man that patch "pset" in Linux, I ask that
contact me.....

let me know if you get any responses, I have also tried
to get information about the "DMAness" of scsi request
without any luck.

Can anyone recomend a decent bug tracking tool that will work with a
Linux server and NT client systems?
Thanks in advance

I have PII 233Mhz system (multiple SCSI / IDE drives, 98MB RAM) running
Slackware kernel 2.0.36. I've allocated a 120MB partition to as swap and
have it automatically utilized a system bootup via the /etc/fstab entry.
When my system gets tearing, it can really eat into the system memory.
Sometimes it freeze or start running slowly because it never utilizes
the swap space when it's used up the free memory. when I type the "free"
command, it shows the though memory is used up and still the swap space
( which regesters in the output of that same command ) nevers gets used.
I utilized partitions on other drives, to ensure that the first was not
bad, to no avail. Is there anything special I need to do get the swap to
be utilized once physical memory is used up ? I've tried manually
running the swapon/off commands also to no avail. Has anyone run into
this ? If so, how did you fix it ? Thanks.

Does 2.0.36 still have the old 128MB swap partition size limit?

I have a plan to reformat my partition table to add swap space. I've
listed my scheme below.
Will it work? Please email or post comments. Your thoughts could save
me tons of time.
Thanks,
Mark
Plan:
I don't wan't to reformat the whole disk.
I may be able to use a program like Partition-It, but would prefer not
to.
If possible, I would like to repartition just the blocks currently in
the dev/hda1 (Blocks 1-131)
Here is my current setup:
Device Boot Start End Blocks Id System
/dev/hda1 1 131 1052226 b Win95 FAT32
/dev/hda2 132 1232 8843782+ 5 Extended
/dev/hda5 132 144 104391 83 Linux native
/dev/hda6 145 863 5775336 83 Linux native
/dev/hda7 864 1080 1743021 83 Linux native
/dev/hda8 1081 1170 722893+ 83 Linux native
/dev/hda9 1171 1190 160618+ 83 Linux native
/dev/hda10 1191 1206 128488+ 82 Linux swap
/dev/hda11 1207 1219 104391 83 Linux native
/dev/hda12 1220 1232 104391 83 Linux native
I want to create something like this:
Device Boot Start End Blocks Id System
/dev/hda1 1 1232 8843782+ 5
Extended <----- note change
/dev/hda2 1 15 128488 82 Linux
swap <----- note change

/dev/hda10 1191 1206 128488+ 82 Linux swap
/dev/hda11 1207 1219 104391 83 Linux native
/dev/hda12 1220 1232 104391 83 Linux native
Is it just as easy as changing the table? Will I aslo need to do
anything about the FAT32 system
or will that happen automatically when the partition table is written?
Any thoughts?

My understanding of kernel interals is simple but progressing.
Can this happen as a result of user sending SIGINT to a process?

man 2 write says this (under the errors section):
EINTR The call was interrupted by a signal before any
data was written.
That's pretty specific, but I wonder how portable code that relies on that
would be...

Well, Debian GNU/Linux has a neat little utility called apt-get(8). You
provide a list of servers that you want to use. Then it scans your
packages and finds a list of packages that need to be upraded. It does it
all for you, and handles the dependancies for you. It will tell you how
much space the new packages will take, and how long it will take you to
get them all.
Gee... this sounds suspiciously like MandrakeUpdate...

Methinks Debian has the prior claim, and Mandrake has pinched their idea

I think you can't do that from the .a file,
as far as I know you have to recompile all files with
specific code generation flags (see -fpic/-fPIC options in the gcc info)
If you use automake / autoconf the easiest way to create a
shared library is to use the 'libtool' package.
Add AM_PROG_LIBTOOL to your configure.in,
and in your Makefile.am define the target as
lib_LTLIBRARIES=mylib.la
(The l is no typo)
Autoconf should take care of the rest.
(Actually I don't know where libtool is located in the internet,
but it should ship with any distro.)
