You also said on IRC: > [John Baldwin had a look at it at USENIX, and he figured it > was a cable or controller problem, which means the system board] If we can establish that the problem is isolated to a specific ATA controller revision, we may be getting somewhere.... My T40, which does not demonstrate any of these problems, has the following: atapci0@pci0:31:1: class=3D0x01018a card=3D0x052d1014 chip=3D0x24ca8086 rev=3D0x01 hdr=3D0x00 A locally affected T41 has the following: atapci0@pci0:31:1: class=3D0x01018a card=3D0x052d1014 chip=3D0x24ca8086 rev=3D0x01 hdr=3D0x00 =2E..which are again, identical. Your T41 is... off to the shop for a motherboard replacement. What I'd like to do next is for people with affected machines to run acpidump, extract their DSDT, and then run md5 to at least establish if they're different; and following on from THAT, to run iasl and diff for possibly differing ACPI methods with regards to the CD-RW module. In the absence of detailed dumps, this is all I can think of right now. This gets us no further to a working hypothesis, but I'm posting this for the sake of having more data to work from.
