Hi Dan,
While I was debugging file system crash with AMCC ADMA driver , I
noticed that async_tx_clear_ack() never been called. Where is the
async_tx->flags is cleared up on completion of DMA transfer ? Looks like
this not cleared and I am hitting the BUG_ON() in async_tx_submit(). If
I call async_tx_clear_ack() in ppc4xx_ adma_free_slots() function
everything seems working fine .
This doesn't sound normal something is going on. Somehow descriptors are
allocated even though they are not free .
Thanks and Regards,
Marri
