SubjectPROBLEM: 3c509 driver broken in 2.4.0-test10, not in -test9
Date

Sorry for using this address, there does not appear to be a special maintainer
for the 3c509 network driver.

1.
3c509 driver broken in 2.4.0-test10, not in -test9

2.
The 3c509 network driver worked fine for decades almost ;-) that is 2.0.x,
2.2.x, and 2.4.0-test up to 9. In 2.4.0-test10 it ooooopes upon modprobing.
lsmod says "initializing" in the 3c509 entry, forever.

3.
3c509, 3C509, Ethernet, networking, 2.4.0-test10

4.
Linux version 2.4.0-test10
compiled by root@arisia (#3 Fri Nov 17 22:37:22 CET 2000)
using gcc version 2.95.2 20000220 (Debian GNU/Linux)

eth0 was not installed by the driver, ifconfig does not find it.

X.
Three notes.

I thought the 3c509 driver would very rarely see any changes. Apparently a
recent one broke it, since with -test9 all was ok.

The 3c509 is configured to use interrupt 15. Both IDE channels are
disabled in the BIOS, IDE support is _not_ compiled into the kernel.
In 7.4 you can see the interrupt was not registered by the driver.

The 7.4 /proc/ioports output shows a line that puzzles me:
> Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II]
I suppose this means parts of the chipset. However I use an old Asus
P55T2P4 mainboard with the 430HX chipset. I believe Natoma/Triton was a
lot later ? So I wonder if the chipset recognition is faulty. After
writing this up, I will reboot with -test9 and check what it recognized
then. I'll add a sequel to this mail if it's different.

Cheers Peter
