Hi I have just succeded in hosing my hard disk for the second time using ports/audio/tosha and my nec SCSI CDROM drive. Symptoms: I try to read an audio track from the CDROM drive, and I get the following errors logged to the console: Sep 1 21:31:26 greenpeace /kernel: st0: BLANK CHECK req sz: 1 (decimal) asc:0,5 End-of-data detected Sep 1 21:31:26 greenpeace /kernel: st0: BLANK CHECK req sz: 1 (decimal) asc:0,5 End-of-data detected Sep 2 07:50:27 greenpeace login: ROOT LOGIN (root) ON ttyv2 Sep 2 08:43:09 greenpeace /kernel: cd0: ILLEGAL REQUEST asc:64,0 Illegal mode for this track Sep 2 08:43:09 greenpeace /kernel: cd0: ILLEGAL REQUEST asc:64,0 Illegal mode for this track Sep 2 08:43:13 greenpeace /kernel: cd0: ILLEGAL REQUEST asc:64,0 Illegal mode for this track Sep 2 08:43:23 greenpeace /kernel: cd0: ILLEGAL REQUEST asc:24,0 Invalid field in CDB Sep 2 08:43:13 greenpeace /kernel: cd0: ILLEGAL REQUEST asc:64,0 Illegal mode for this track Sep 2 08:43:23 greenpeace /kernel: cd0: ILLEGAL REQUEST asc:24,0 Invalid field in CDB Sep 2 08:45:21 greenpeace /kernel: cd0: SCB 0x0 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 Sep 2 08:45:21 greenpeace /kernel: cd0: SCB 0x0 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 Sep 2 08:45:22 greenpeace /kernel: SEQADDR = 0x6 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa Sep 2 08:45:22 greenpeace /kernel: SEQADDR = 0x6 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa The system hangs, and after a while panics. The SCSI disk on the same bus is then HOSED - it needs to be low level reformatted, as a very large number of sectors are not readable. I have a GA586DX motherboard, which has an Adaptec 7660(?) on board. (This is the chip that looks like a 2940.) I am running 3.0-CURRENT (Really current). I did not have this problem 2 weeks ago. (Last time I tried.) Hints? Suggestions? Flames? I can't experiment too much, as it takes me several hours to recover each time. (I love DAT!)
