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 ...)
