Hi Finn,
thanks, doing that now. The log is on IDE so no danger there. My debug
code along with esp_debug = ESP_DEBUG_RECONNECT shows the code path is
exercised by the single disk attached to elgar.
Contrary to the Mac driver, esp->command_block and
esp->command_block_dma are not identical addresses on Amiga. Is there
a generic way to map a DMA address (i.e., physical address AFAIK) to a
kernel virtual one? (I can use esp->command_block in the reconnect
message special case but not otherwise ...)
Cheers,
Michael

Hi Tuomas,
fair enough - I'll get the PIO code tested by forcing PIO transfers on
elgar, and submit the driver for review once that's done.
You might need to instrument the esp_reconnect_with_tag() code path to
confirm that elgar's scsi disks exercise the new code. I'd probably just
set esp_scsi.esp_debug=0x200 (that is, ESP_DEBUG_RECONNECT). But watch out
for /var/log/kern.log, in case it is on a scsi disk...

Maybe someone else has a chance to test the fix in the meantime.
