No.. the laptops are certified too. Not all the software on them I think,
but the hardware is definitely restricted and often modified.

The shuttle computers are designed for ONE task -- flying the spacecraft.
They are not designed to read email or play quake3. FWIW I do not think
you would WANT the shuttle computers doing anything else - these are
specially designed hard realtime triple redundant systems quite different
from laptops.

FWIW if you read the public records of space station and shuttle logs,
it's downright scary how often m$ stuff causes big problems up there.

Ive found a number of problems can be traced to power supply problems, the
board providing a bit of under voltage. Manually adjusting CPU voltage a
notch or two up has fixed many a board for me.

Also manually adjusting SDRAM drive strength can help, BIOS sometimes gets
this wrong.

UDMA has crc, scsi has parity, pci has (i think) parity, tcpip has crc,
your cpu l1 and l2 have ecc...

Looks like similar checks are already there.

Thats the hardware FIFO size. The chained descriptors can of course handle
much larger data.

FWIW 10/100 chips usually only have 32-128 bytes hardware FIFO, so
32kbytes hardware FIFO is pretty generous.

I have seen that many drives either have a pathetically small queue or

I know both good and bad people at corporations. The bad people were mean
and nasty before they joined the corporation, the corporation became a
vehicle for them to abuse others and directly translated to the
misbehaviour of that corporation. Doing bad things comes naturally to
them.

The good people went out of their way to prevent the corporation from
doing evil things, or left the corporation so they would not be party to
the unethical behaviour.

Probably they did not pursue because they knew their patent was invalid,
and if they did fight they would probably be found guilty of bad faith
patent enforcement - treble damages, the whole bit. And maybe criminal
fraud, if they had collected enough money under the bad patent.

The XOR patent and the fraudulent enforcement of it is the purest
embodiment of everything that is wrong with the patent system and IP law.

 Actually, it's because we've made it illegal to corporations to behave
 ethically when it conflicts with short-term shareholder profits.
 http://www.ratical.com/corporations/
 It would be nice if it were so simple as to declare the involved parties as
 evil.

I know both good and bad people at corporations. The bad people were mean
and nasty before they joined the corporation, the corporation became a
vehicle for them to abuse others and directly translated to the
misbehaviour of that corporation. Doing bad things comes naturally to
them.

The good people went out of their way to prevent the corporation from
doing evil things, or left the corporation so they would not be party to
the unethical behaviour.

3ware 6400 ATA-RAID bugs

2001-02-17 Thread Dan Hollis

Kernel 2.4.1-ac15, 3ware driver.

512mb ram, amd thunderbird 1000, 3ware escalade 6400 with 2 x 45gb IBM
in raid5 mode.

'iozone 512 16384' is a guaranteed, repeatable way to totally kill this

The kernel starts spitting out a zillion of

And then it starts going endlessly into a loop of

"3w-: tw_scsi_eh_abort(): Abort failed for unknown Scsi_Cmnd 0xe7da6e00, resetting

You can program the northbridge to generate NMI or not, on ECC errors.
Most chipsets still need to scrub memory after an error to reset ECC bits.

So we should have different system calls just so one can handle socket
and one can handle disk fd? :P

Ok so now will have special case sendfile() for each different kind of
fd's.

To connect socket-socket we can call it electrician() and to connect
pipe-pipe we can call it plumber() [1].
