If the 'poweroff' command doesn't hang after the oops, aranym will log "write cmd 0xE0 (STANDBY IMMEDIATE) not supported". I think I once saw it log an attempt to read beyond the end of a device but I'm having trouble reproducing that. The "hdb: lost interrupt" messages from Linux might be important. The new libata driver doesn't use the ST-DMA interrupt sharing mechanism and Adrian's results suggest this driver works okay with Aranym's IDE CD-ROM emulation. -- > Andreas. > >
