Might some hd.c guru tell me a possible cause for the following errors?

Here I was running 1.0.9:

        Jul 20 02:27:18 crash kernel: HD: write_intr: status = 0x51
        Jul 20 02:27:19 crash kernel: HD: write_intr: error = 0x04
        [repeats 10 times]

And here, 1.1.33:

        Jul 27 01:24:41 crash kernel: HD: write_intr: status = 0x51
        Jul 27 01:24:41 crash kernel: HD: write_intr: error = 0x04
        [repeats 4 times]

Both of these resulted in a filesystem crash with lockup.
In both occasions I was abusing the system pretty bad: Kernel compile
+ X + PPP + FTP + rlogin + xv.

Hardware:
386-DX/33, 6 MB RAM, 210 MB Maxtor IDE drive.

Thanks

I think somthing nice for you would be tkined wich is a simple tk-based
network-administration-tool. You can layout your network with icons and
name/adresses of the node. You are also able to get ip- and
snmp-informations if you are running an snmpd on that node.

I tried the snmpd from the cmu-snmp-package (I think version 2.0, with
MIB-II) and it worked for me doing only local loopback.
But I think it will be working on complex networks.
I tried it with an RM600(SNI MIPS R4400 Machine) from a LINUX-box and
it works with the snmp-agent of this machine.

So ask archie for tkined and cmu-snmp and you will get what you want.

Happy SNMP

The chipset is 5434, but if you want to use it under XFree86 2.1
you have to write 'chipset = cl5424' in the Xconfig file.
If you use another cirrus chipset the bitblt engine will crash the server
(at least it crashed on my computer).

You have to use 'X probeonly' (or something like that, I can't remember
the command) to calculate the clocks.

Anyway I hope I can use my Kelvin PCI card at full speed SoOoN !!!

A new stack at the same location means that you can't put things on the
stack if any other thread might need them. Ugly.

Yep. In fact, changing clone() to just create a new stack area should not
be too difficult. Just tell it how much space to keep for the old stack.
The new process will probably get a segmentation fault if it tries to
return from the procedure you're calling with clone(), but that's OK, IMHO.

So implement it and send the patches to Linus. The framework is already
there, so it is rather easy.

If you want to extend the original memory map, the way clone() works now
makes sense. Mostly. ;-)

It has been fixed for a long time (since 1.1.0, at least, and probably
even since some of the 1.0.x kernels). We are using 1.1.24 with a
2-bit subnet field, so it definitely is working now.

re: lockups, I only get them when the buffer cache gets full and it's

that I did notice with the newest driver and 1.1.35, is this:

IN-2000 probe found hdw. vers. 27, BIOS at 0c8000

it doesn't seem right to me that both are scsi0.  I've tried jumpering the

For starters, see the 'man' pages on ioctl, termios, fcntl, open,
and of course their 'SEE ALSO' cross references.  Other useful
information is found in man setserial and Serial-HOWTO.gz, found
on Slackware in /usr/doc/faq/howto.  As to using the control

*BSD does support shared R/W access to mmaped data.  Buut, the data will
not normally be totally consistant with the buffer cache.  FreeBSD V2.0
will fix it (and probably be the first *BSD that supports the coherency.)
 
The data will be consistant between mmaps however.

To whoever is interested in putting a PCMCIA C&S into Linux, I have a
request.  Please put the PCIC code into the kernel and have it program
the PCIC before allowing the SCSI drivers to load.

The reason for this is to allow SCSI PCMCIA cards to be recognized and
configured to allow the SCSI driver to be able to load without
source modifications (to configure the card via the PCIC).

If someone wants to do this, then the 1522 driver can support the SCSI
PCMCIA I have without modifications: New Media SCSI Bus Toaster.

In the meantime, I'm going to try whacking the card by putting the
PCIC code into the 1522 driver.
