This breaks most of my Linux tests. *BSD are unaffected. For example sparc-test 2.0: eth0: LANCE 52:54:00:12:34:56 esp0: IRQ 36 SCSI ID 7 Clk 40MHz CCYC=25000 CCF=8 TOut 167 NCR53C9XF(espfast) ESP: Total of 1 ESP hosts found, 1 actually in use. scsi0 : Sparc ESP100A-FAST esp0: Aborting command esp0: dumping state esp0: dma -- cond_reg<a4400311> addr<f0010e64> esp0: SW [sreg<11> sstep<04> ireg<18>] esp0: HW reread [sreg<93> sstep<00> ireg<10>] esp0: current command [tgt<02> lun<00> pphase<CLUELESS> cphase<DATAIN>] esp0: disconnected esp0: Aborting command esp0: dumping state esp0: dma -- cond_reg<a4400310> addr<f0010e64> esp0: SW [sreg<11> sstep<04> ireg<18>] esp0: HW reread [sreg<03> sstep<04> ireg<00>] esp0: current command [tgt<02> lun<00> pphase<UNISSUED> cphase<UNISSUED>] esp0: disconnected esp0: Resetting scsi bus esp0: SCSI bus reset interrupt esp0: Aborting command esp0: dumping state esp0: dma -- cond_reg<a4400211> addr<f000d007> esp0: SW [sreg<03> sstep<04> ireg<80>] esp0: HW reread [sreg<91> sstep<04> ireg<18>] esp0: current command [tgt<02> lun<00> pphase<UNISSUED> cphase<UNISSUED>] esp0: disconnected scsi: Device offlined - not ready after error recovery: host 0 channel 0 id 2 lun 0 Since Open/NetBSD still works, there may be yet again another bug that your patch uncovers.
