Well that surely shouldnt happen...I use minicom all the time (I still
call BBSes), and havent had any crashes.  I can quit/disconnect, or 
quit/stay connected and it works okay.   I've even got it set up to
use 23bps, which is the max my Zoom will take.

When I was trying to set up the ESP shortly after I'd received it,
there was some trial+error to get the address/irq/dma/jumpers set right,
and minicom would hang (the program), but I could kill it.  It took about
an hour to get the settings the way I'd wanted them, and since then...
no real problems.

I also have a SB16 (non-PnP).  I use DMA 1 and 5 for the SB16 and 3 for
the ESP.I dont know if it's doing anything though...wish there were a
way to know how deep into the buffers it ever gets on transfers.  DMA
threshold on mine is the default value (I believe it's 32 bytes) -- it
wouldnt suprise me if it didnt get that deep, keeping the rx_threshold
so low.

My modules.conf ESP section looks like:

#
# Hayes ESP module + options
# port 180h, irq 3, dma 3, divisor 4
options esp irq=0,0,3,0,0,0,0,0 dma=3 divisor=0,0,0x04,0,0,0,0,0 rx_timeout=1
post-install esp setserial /dev/ttyP16 low_latency
alias char-major-57 esp
alias chat-major-58 esp

Only troubles it's given me lately is that esp.c isnt a devfs-aware
driver.  I've been experimenting with devfs lately, so I have to do
a "mknod /dev/ttyP16 c 57 16" every time I boot, and it still barks out
a few meaningless errors (cup: device already registered).
I just have the one-port ESP card.

I dont like to be the sort of person who, when people report problems,
fires back "it works fine here!"...but...just as a point of reference,
I have a Hayes ESP too -- it's connected to a 56k modem.  I havent
had any crashes or hangs related to it, but I dont use mgetty.  (I use
rungetty, a variant of mingetty,  for VC's).Seeing this, I will
compile up mgetty here to see if I can replicate it.

(once in a while, communications becomes non-responsive -- but I

reason.  The port seems to be doing it's thing.)

I'm running 2.4.0-ac12 here.   ESP is set to 180h, IRQ 3, DMA 3.
(I disabled my onboard serial ports).   CPU is a classic Pentium.
I've been running it w/  rx_timeout=1  (the minimum usable value,
since it seems to give lower ping times)

Got this ESP off eBay -- in fact, I got it after reading Mr. Jansen's
recommendation 2 years ago in the comp.dcom.* groups (probably ISDN),
noting how flexible and tweakable the ESP drivers are.  FWIW, I was
getting mountains of TCP errors before I got this card, and they all
disappeared once I installed the ESP.  It's an amazing card.

Yeah, I just applied the patch and recompiled.  Yes, it fixed it, pretty
decisively too.

P100/16Mb RAM/17Mb swap -- run Netscape 3.04, and start some large Java
applet -- like a Java-based game or Yahoo Chat or some such.

...on 240-ac4, it works okay.   On 240-ac9, the disk grinds away, and it's

With this patch, it's pretty much back to the way it was in -ac4, maybe a
little better.

2.4.0-ac9 works, but slower and swappier

2001-01-14 Thread Mark Orr


I've been running 2.4.0-ac9 for a day and a half now.

I have pretty low-end hardware (Pentium 1/ 100MHz, 16Mb RAM,
17Mb swap)  and it really seems to bog down with anything
heavy in memory.Netscape seems to really drag, and any
Java applets I encounter positively crawl -- you can see
the individual widgets being drawn.

My previous kernel was 240-ac4, and it was fine.


Oh, one other thing...cat /proc/filesystems shows:

nodev   sockfs
nodev   swapfs
nodev   shm
nodev   pipefs
nodev   proc
ext2
nodev   devpts

I thought swapfs _replaces_  shm?   I mention this because
my startup scripts mount'ed shm the way it always does.
I figured it'd fail because shm wouldnt be there.  I've
since disabled that.

So,  mount swapfs to /dev/shm, and leave the shm filesystem
unmounted?   Go back to the way it was before (mounting to
/var/shm) ??

W/ swapfs (only) mounted,  MITSHM apps like MpegTV, Virtual
Gameboy, Xanim, etc.  seem to work okay.

I applied test13-pre4-ac2 here, and it applied cleanly.
Are you applying it to a clean tree?  Are your using
patch v2.5.4 ?   (that's the version I have)

FWIW, I was getting smp.c patch failures (well, it said the
patch was previously applied) along with a bunch of
IPTables stuff -- that was a couple of -ac's ago.

AC1 and AC2 applied cleanly, tho AC1 wouldnt compile
uniprocessor/no-quotas unless you added a 
#include  to fs/ext2/balloc.c
(i.e. it left some hanging refs to lock_kernel and
unlock_kernel in fs.o,  and I think there was also
one in the UDF module.It's fixed in -ac2.

Heh...do what I did.  Go on eBay and pick up a Hayes ESP card.

I have a fairly weak system by todays standards, and I found that
even with a 16550 serial port, I'd get tcp/ip errors in my logs
(and lots of 'em).

They never wrote decent ESP drivers for Windows, but the
Linux drivers are superb.   I popped it in, configured it,
and the tcp errors vanished...not a single one in the 10 months
I've owned it.

It bugs me that they're making PC's w/o ISA cards now, because
I dont wanna give up my Hayes ESP.   Based on what I saw, a 16550
with it's tiny 16-byte buffer, isnt enough.

(yes, I'm stuck with POTS+PPP.  Cable modems are available...
but the ISP is @Hoax.  Yuck.   The only DSL grade I can get is
IDSL -- $70/month.  Double yuck.)

[2.4.0-test10-pre3] UART401 problem causes Oops.

2000-10-16 Thread Mark Orr


I recently compiled 2.4.0-test10-pre3, and was torture-testing
it...I hadnt played any MIDI files in a while, so while one
was playing (on my waveblaster GM daughterboard, thru UART401),
the gave an Oops.

After doing some detective work, I found that the culprit was a
small daemon I had running that does a "double-rmmod -a" every
X seconds.   It was rmmod'ing the uart401 module while it was
in use.   I confirmed that while the MIDI file was playing, the
lsmod usage count was zero, and I could manually remove it.
(causing an instant oops)

It looks like the UART401 (this is a Sound Blaster 16 ISA non-PnP
card) module is not marking itself used while it's being accessed.

[2.4.0-test10-pre3] UART401 problem causes Oops.

2000-10-16 Thread Mark Orr


I recently compiled 2.4.0-test10-pre3, and was torture-testing
it...I hadnt played any MIDI files in a while, so while one
was playing (on my waveblaster GM daughterboard, thru UART401),
the gave an Oops.

After doing some detective work, I found that the culprit was a
small daemon I had running that does a "double-rmmod -a" every
X seconds.   It was rmmod'ing the uart401 module while it was
in use.   I confirmed that while the MIDI file was playing, the
lsmod usage count was zero, and I could manually remove it.

Re: Linux-2.4.0-test9-pre2

2000-09-17 Thread Mark Orr


Has anyone else tried 240-test9-pre2 on low-memory systems?

I compiled 240t9p2, bzlilo'ed it, and rebooted.  During
boot it tripped up on e2fsck -- it was at maximum mount count
and it stopped during the check.

Once I got past the check, and was able to get it to a prompt.
I tried to compile the kernel modules.  Once again, it stopped
during the compile of the first file (either loop.c or floppy.c).

By "stopped", I mean the _program_ acted as though it had hung.
The system didnt hang, I was able to ctrl-c out of it, and there
was no oops or panic.It doesnt seem to be able to run any
substantial program w/o stopping.

Previous kernel was 240-test8, no problems there.
