System: SLS 0.98.5 with Linux 0.99 kernel (no patches).

Hardware: 386DX40 4Mb RAM, multi I/O controller (LPT2, COM1, COM2, GamePort)
WD ethernet card (8 bit), 130Mb IDE drive.

Problem:

Installation went fine, tcp/ip works in loopback except for telnetd.
Replacing telnetd with an old tinytelnetd I wrote for a sys5.2 machine
fixed that problem.

Ethernet card is not recognized. The kernel parameters seem to match
my setting (0xD0000 Int 2 IO 0x240), and nothing seems to clash.
Booting a floppy which configures the card and then runs ka9q under DOS
works fine. Under linux 0.98.5 simply failed to do anything with the card
0.99 denies it exists.

HELP!!!!

I'm seeing problems with 0.99pl1 and tcp/ip with the p0-p5 patch.

1)	Connects to serverless ports are not refused
2)	Like someone else saw it sometimes decides it will no longer
	output to a socket.. although input is working
3)	ftp is very fast, but a while after any big ftp's the
	computer falls over. I don't know why , it doesn't have
	a monitor, but it seems fairly reproducable

Hardware: 386DX40 4Mb RAM, WD 8 bit card 0xD8000 0x320 irq 7

A footnote: When it hangs under heavy load it can corrupt your disk.

Fortunately it didnt eat too much.

I've done some more checking. TCP output totally freezes at about the
point the machine starts swapping. The odd thing is that its only _DATA_
that gets lost, the connection still occurs.

Do you mean this is common to all TCP freezes, or does swapping
co-occur with locking only when you lose data?

When my telnet locks, it is only the output (at least at first). Input
works normally. Never checked any kernel messages or done debugging
before, but last time there were two "wd8003 timed out" messages.

Swapping/Lockups:
	Dunno where that came from thst was sent early january, although I've
not fixed it and any info would help. Hopefully the machine Im using on
the internet will have a monitor on it now.

Another Bug:
	Create a socket, connect to a non-existant host, and while it's
trying to connect set an alarm off and then in the signal handler write
to the socket. Goodbye linux box.
