Re: failing disk, or not?

This doesn't sound like a disk failure to me. It sounds like a driver
problem.
:atapci1: <Generic PCI ATA controller> port 0xec00-0xec7f,0xeb00-0xeb0f,0xb70-0xb73,0x970-0x977,0xbf0-0xbf3,0x9f0-0x9f7 irq 11 at device 10.0 on pci0
:ad4: DMA limited to UDMA33, non-ATA66 cable or device

That's not good. It can't identify the controller. It's amazing that
it works at all.
Could you run pciconf -l?
:A bit of history, I did have a system lockup -- I could switch virtural
:terminals but no keyboard input was accepted -- a week or two ago,
:didn't file bug because I was half-hazard experimenting (in user space)
:and couldn't explain well enough, at the time all I was doing, now I
:don't even remember. A fsck was required, and with a 95Gb /usr, that
:took quite a while. (welcome comments on why softupdates didn't help
:here), also the /usr partition was near or over 100% capacity, but I
:never got disk full errors, ie didn't *completely* run out of space.
:
:At this point can I be sure my disk is failing or could there be some
:driver instability? The full dmesg is below.

:Don't see it in dmesg, but ad4 is a 200Gb Seagate drive, on a nvidia
:sata controler. Disk Product Number ST3200822AS, Part Number 9W2854-301

:Thanks,

Update to the latest, just in case recent big fixes might have
something to do with the lockup you experienced.
Softupdates does not prevent fsck from running. We don't have a
solution at the moment. FreeBSD has implemented a background
fsck but I just don't like that solution.
