I've replaced a power supply that was almost certainly marginal (kernel page fault failures during fsck on two drives at once, but not on one at a time) and put a brand new SATA DVD burner on the machine (LITE-ON iHAS124-04). uname -a reports FreeBSD silver.local 7.2-RELEASE FreeBSD 7.2-RELEASE #5: Thu May 20 09:45:44 EDT 2010 toor@silver.local:/usr/obj/usr/src/sys/SMP-GONDOLIN i386 Power supply is a new 400W Rosewill; MB is by Asus, processor is a Core 2 Quad running at (I think) 2.25 GHz. (It's under 2.3.) I added an MSI GeForce video card (X doesn't want to run on the mobo video). There are two SATA disks, both 7200 RPM and neither in service for very long. (I only buy 5-year-warranty drives.) They are in a carrier with a fan and are cool to the touch. The processor cores run between 49 and 57 C; the NB chip has a big copper heat sink with an 8 CFM fan; HS is warm at the bottom and cool at the top. This worked a few weeks ago, when I burned about forty of these "Archival Gold" disks. cdrecord -v reports that they have the same chemistry and write strategy as the TDK cheapies. I've tried with both atapi/cdburn and atapicam/cdrecord. I've tried with both TDK CDs and the expensive archival-grade discs I'm trying to burn. The operation pauses for a very long time, the activity LED on the drive flashes, and I get console messages thus: Aug 14 07:03:50 silver kernel: acd0: TIMEOUT - WRITE_BIG retrying (1 retry left) Aug 14 07:03:50 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:03:51 silver kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly Aug 14 07:03:51 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:04:31 silver kernel: acd0: WARNING - unknown CMD (0x4a) taskqueue timeout - completing request directly Aug 14 07:04:31 silver kernel: acd0: WARNING - unknown CMD (0x4a) freeing taskqueue zombie request Aug 14 07:04:51 silver kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly Aug 14 07:04:51 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:08:13 silver kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly Aug 14 07:08:52 silver kernel: acd0: TIMEOUT - WRITE_BIG retrying (1 retry left) Aug 14 07:08:52 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:08:53 silver kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly Aug 14 07:08:53 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:09:33 silver kernel: acd0: WARNING - unknown CMD (0x4a) taskqueue timeout - completing request directly Aug 14 07:09:33 silver kernel: acd0: WARNING - unknown CMD (0x4a) freeing taskqueue zombie request Lather, rinse, repeat. Sometimes it makes it to the end of the disk, more often with the cheap disks that with the $2.00-to-burn-a-coaster archival disks. I get about the same messages whether using atapi or atapicam. I have had the whole machine lock up twice. Once it was apparently a disk system lockup; I could get prompts but nothing would run. It freed up, apparently after something was run, the other time it stopped responding to the console keyboard in any way and nothing moved on the display. The drive seems to only want to write at speed 48. Using cdrecord speed=0 (use slowest available) is runs at the same 48 that it runs at with no speed= . I will be grateful for any suggestions.
