Hi all,
I am integrating the e100.c driver to one of my application specific network
protocol stack which runs as a kernel module.
The ethernet controller used is Intel 82562.
Kernel version is 2.6.33.7
When I insmod my kernel module, It will initialise the e100 driver too. My
system freezed after inserting the module.
By using printks I found that the freeze happens during the call to the
function e100_enable_irq().
The function has a iowrite
iowrite8(irq_mask_none, &nic->csr->scb.cmd_hi);
When I comment the above line, there is no system freeze. But the interrupts
aren't enabled, which is obviously of no use to me :)
I would like to know
i) Why the system freezes when i enable the IRQ. My IRQ number for this
ethernet controller in my system is 20.
ii) How to solve this system freeze?
I would be happy to provide more inputs if needed.
