RE: Interrupts disabled


I think it is caused by a timer that reads the current Ethernet
speed. The Ethernet speed is read with a slow I2C protocol from
the tranceiver. 

In elinux/drivers/net/e100net.c you will find the following rows:

speed_timer.expires = jiffies + NET_LINK_UP_CHECK_INTERVAL;
speed_timer.function = &e100_check_speed;

Try to remove these lines of code.

I'm trying to use the Etrax100 developer card for data acquisition in 10
kHz, but it seems that somebody disables interrupts for about 650 us every
2 seconds. Does anybody have a clue where this is done?
