So I change my script,the sja1000_isa line is now :
try 1 : insmod
/lib/modules/2.6.32.11-target-alpha-v2/kernel/drivers/net/can/sja1000/sja1000_isa.ko
irq=5,7 mem=0xD0000,0xD0200 ocr=0x5e,0x5e
try 2 : insmod
/lib/modules/2.6.32.11-target-alpha-v2/kernel/drivers/net/can/sja1000/sja1000_isa.ko
irq=5,7 mem=0xD0000,0xD0200 ocr=0x5e,0x5e cdr=0,0
Nothing is plugged into my card (no wire and no resistors). I did :
candump any,0:0,#FFFFFFFF (in a first terminal)
cansend can0 5A1#11.22 (in a second one)
cat /proc/interrupts
And nothing seems to have changed

I don't know what kind of report you'll need (dmesg ? interrupts ? iomem ?
stats ? ifconfig ? ...)
