This time I'm using my own compiled 2.4.13 kernel. If it helps, I'll upgrade
to 2.4.16.
My /proc/interrupts without your new ioblix module:

With the above line, I get the following:
RBM IOBlix card (#0)
at address 0x80e90000, size 0x10000.
Ethernet bit status WAS OFF
Ethernet bit status is OFF
ttyS1 at 0x80e91000.
ttyS2 at 0x80e91080.
ttyS3 at 0x80e91100.
ttyS4 at 0x80e91180.
This is my /proc/interrupts with the module loaded as above:
ami 0: 183587 console/cursor
ami 1: 0 <NULL>
ami 2: 0 <NULL>
ami 3: 0 <NULL>
ami 4: 0 <NULL>
ami 5: 0 <NULL>
ami 6: 0 <NULL>
ami 7: 0 <NULL>
ami 8: 0 floppy_dma
ami 9: 0 F serial RX
ami 10: 0 serial TX
ami 11: 0 <NULL>
ami 12: 23459 eth0
53c7xx
cia 14: 0 <NULL>
cia 15: 0 floppy_timer
cia 16: 0 <NULL>
cia 17: 1505 keyboard
cia 18: 0 <NULL>
cia 19: 0 <NULL>
cia 20: 0 <NULL>
cia 21: 0 <NULL>
cia 22: 0 <NULL>
cia 23: 0 <NULL>
As you can see, there is no difference between this and the interrupt list
without the module.
This is my /proc/iomem with the module loaded:
00000000-001fffff : Chip RAM
00000000-00007fff : Floppy
001ff000-001fffff : Beep

ef000000-ef01ffff : Texas Instruments TVP4020 [Permedia 2]
ef010000-ef01ffff : pm2fb
As you can see, the driver is now listed just below the IOBlix entry.
And this is my /proc/tty/drivers with the module loaded:
RBM_IOBlix /dev/cua 5 65-68 serial:callout
RBM_IOBlix /dev/ttyS 4 65-68 serial
amiserial /dev/cua 5 64 serial:callout
amiserial /dev/ttyS 4 64 serial
pty_slave /dev/pts 136 0-255 pty:slave
pty_master /dev/ptm 128 0-255 pty:master
pty_slave /dev/ttyp 3 0-255 pty:slave
pty_master /dev/pty 2 0-255 pty:master
/dev/vc/0 /dev/vc/0 4 0 system:vtmaster
/dev/ptmx /dev/ptmx 5 2 system
/dev/console /dev/console 5 1 system:console
/dev/tty /dev/tty 5 0 system:/dev/tty
unknown /dev/vc/%d 4 1-63 console
> insmod ioblix iob_ether=1
Now, with the above parameters, the ONLY difference is this message:
RBM IOBlix card (#0)
at address 0x80e90000, size 0x10000.
Ethernet bit status WAS OFF
Ethernet bit status is ON
ttyS1 at 0x80e91000.
ttyS2 at 0x80e91080.
ttyS3 at 0x80e91100.
ttyS4 at 0x80e91180.
I did notice one other strange thing though, and that was when I rmmod'ed the
module. I get the following every time I rmmod ioblix:
amiga_delete_irq: tried to remove invalid irq
My amiga still hangs when trying to access any of the serial ports of the
IOBlix.
Thank you for your help.
