Hello Paul
Check an old topic on the list "net2280: tracing", where Jorge
Ramirez-Ortiz and Felipe Balbi are working on tracing the chip

Ricardo,
I think I figured out the problem: my 3380 was running in legacy adapter mode.
I am now capable of connecting both g_mass_storage and g_ether without any
kernel panics after ensuring the 3380 is in enhanced adapter mode.
My only concern is the speed from my Mac to Linux:
- g_ether: scp
Ricardo,
Unfortunately your latest change gives similar results, cycling errors in the
log:
[ 201.287706] [ cut here ]

One last try :)
Instead of:
if (likely(t & BIT(FIFO_EMPTY))) {
have this:
if ( t & BIT(NAK_OUT_PACKETS)){
count = readl(&ep->dma->dmacount);
count &= DMA_BYTE_COUNT_MASK;
break;
}
if (likely(t & BIT(FIFO_EMPTY))) {

Ricardo,
it no longer locks up but if I try to write to the drive, I get cycles of:

Could you try
if (likely(t & (BIT(FIFO_EMPTY) | BIT(NAK_OUT_PACKETS{
instead of
if (likely(t & BIT(FIFO_EMPTY)))
And tell if it works better

hmm it seems that the code is waiting for a dma to complete. Please print
ep->dma->dmactl
ep->dma->dmastat
ep->dma->dmacount
ep->dma->dmadesc
req->td_dma
ep->regs->ep_stat
Thanks

Ricardo,
count = 0, req->valid = 1, le32_to_cpu(req->td->dmacount) = 2952791040

Could you print
count, req->valid and le32_to_cpu(req->td->dmacount) just before udelay(1)
Thanks!

Ricardo,
I added a ep_warn before and after the loop and right after connecting my Mac
it passes through that loop many times.
Even without writing to the device I then get the lockup message while inside
the loop (ep->dev = ep-b).

Hello
Could you check if the code is stalled at this loop ?
