Here's a traceback from my here are my observations: I have a T30 running -CURRENT from May 25th and i was able to test with two cdrw drives. one worked (almost) perfectly, the other one i consider broken after the results of my tests. i was always able to boot, never got a panic. with the broken drive, i got the ata1-slave: FAILURE - ATAPI_IDENTIFY no interrupt errors others are seeing. the non-broken one did not show any errors during boot. with the non-broken one, i was able to write several cd-r in a row. i verified all of them, they are fine. i used burncd -e -s max data image.iso fixate to burn them. after the last burn, however, i got these errors when i tried to mount the cd-r (no errors during burn, however): kernel: acd0: WARNING - REQUEST_SENSE read data overrun 18>0 last message repeated 58 times i rebooted the machine and was then able to mount and read the same cd-r without an error. so this is were a bug in FreeBSD might be. now the errors the broken drive showed during both writing and reading: kernel: acd0: FAILURE - READ_TRACK_INFO ILLEGAL REQUEST asc=0x24 ascq=0x00 error=4<ABORTED> kernel: acd0: WARNING - REQUEST_SENSE read data overrun 18>0 last message repeated 58 times kernel: acd0: FAILURE - REQUEST_SENSE MEDIUM ERROR asc=0x0c ascq=0x00 error=4<ABORTED> kernel: acd0: WARNING - REQUEST_SENSE read data overrun 18>0 last message repeated 58 times luckily, my broken drive still is on warranty. damn shame they break so easily, i harldy used it and do not take it with me when moving around with the laptop most of the time. hopefully, my obervations helped anyone. cheers, t.home | help
