Looks like PIO at unaligned addresses doesn't work on alpha...

           Summary: kernel 2.6.10-2.6.16 on alpha: arch/alpha/kernel/io.c,
                    iowrite16_rep() BUG_ON((unsigned long)src & 0x1)
                    triggered
    Kernel Version: 2.6.16
            Status: NEW
          Severity: blocking
             Owner: [email-masked]
         Submitter: [email-masked]

Most recent kernel where this bug did not occur: 2.6.10 (i think so)

Distribution: self build (RH9, FC4/5 on alpha mix) 
Hardware Environment: alpha sx164pc board with ne200 ISA card.
Software Environment:
Problem Description:

Since 2.6.10 the BUG_ON() in arch/alpha/kernel/io.c iowrite16_rep() 
is triggered randomly, but reproducable on linux alpha platform with
ne2000/8390 ISA network card.

NE*000 ethercard probe at 0x320: 00 80 29 63 4a f6
eth%d: NE2000 found at 0x320, using IRQ 5.

I´ve traced this back to drivers/net/8390.c:
 ei_start_xmit().
I add a workaround, because else the system won't be usable any more in
ei_start_xmit() like this:
  if ( (unsigned long) skb->data & 0x1)
        {
                printk(KERN_WARNING "ei_start_xmit(): skb->data unaligned %p
align to %p length %i\n", skb->data, scratch, send_length);
                if ( send_length >= 128 ) goto normal;
                memset( scratch, 0, 128);
                memcpy( scratch, skb->data, send_length < 128 ? send_length : 128);
                ei_block_output(dev, send_length, scratch, output_page);
        }
        else
        {
normal:
            ei_block_output(dev, send_length, skb->data, output_page);
        }
And the output in the kernel ring buffer is:
dmesg | grep xmit
ei_start_xmit(): skb->data unaligned fffffc0019be55d5 align to fffffc001ef37620
length 60
ei_start_xmit(): skb->data unaligned fffffc0019be55d5 align to fffffc001ef37620
length 60
ei_start_xmit(): skb->data unaligned fffffc0008ceb735 align to fffffc00019dbb18
length 60
ei_start_xmit(): skb->data unaligned fffffc000ea787c5 align to fffffc001f683540
length 60
ei_start_xmit(): skb->data unaligned fffffc000e864fe9 align to fffffc000b737350
length 60
ei_start_xmit(): skb->data unaligned fffffc0008cd883f align to fffffc000b737350
length 60

So why is the skb->data address unaligned over time the system is running?

Steps to reproduce:
Every time. I think with higher system load the BUG is triggered earlier.

Here some stack traces with BUG_ON/ WARN_ON added by me in more places to trace
down the problem:
