No luck with that patch. I applied it, but it did not hit
that condition. It made it all the way to the code just
before the label "chain_done:". I insert printks all over
the place to figure out where it goes. It failed somewhere
in here because I got a printk just before it, but I did not
get the printk immediately at chain_done. I applied it to
12.0.0. The print just before the for loop was the last I
saw and then it hung.
for (i = 0; i < ioc->chain_depth; i++) {
ioc->chain_lookup[i].chain_buffer = pci_pool_alloc(
ioc->chain_dma_pool , GFP_KERNEL,
&ioc->chain_lookup[i].chain_buffer_dma);
if (!ioc->chain_lookup[i].chain_buffer) {
ioc->chain_depth = i;
goto chain_done;
}
total_sz += ioc->request_sz;
}
