Hi David and others kernel developers,
Thanx for your pcnet_cs driver! I use it since old days :-P
I bought a IC-CARD+ pcnet_cs compatible pcmcia nic, and i'm using it on a
StrongARM HP Jornada 710. My kernel is a 2.4.18-rmk3-hh10 and my pcmcia-cs
version is 3.1.33
From dmesg I got this messages:
--

Any suggestions?
I tried to change some values in pcnet_cs.c:
INT_MODULE_PARM(use_big_buf, 1); /* i tried 0 */
INT_MODULE_PARM(delay_output, 0); /* I tried 1 */
INT_MODULE_PARM(delay_time, 4); /* I tried 6 */
but no change helped...
bye,
rafael diniz

This looks like a case of the old 2.4 interrupt handling problems
which got resolved by rewriting the ARM interrupt handling
infrastructure during 2.5.
The problem occurs because of the need to handle edge-triggered
interrupts (as is the case with Intel CPUs) differently from
level-triggered interrupts, especially when the peripherals are
designed to be used with level-triggered inputs.
In effect, you can end up with the situation where the device has
its interrupt asserted, but because the CPU doesn't see a change
of state, it "forgets" about the interrupt input.
I'm not aware of a solution for this problem with 2.4 kernels.
