I'm running a debian 2.6.26-9 kernel (sid) on a new laptop with:

Soon after booting, and possibly after the disk had spun down and was
asked to spin back up (which it had done successfully a few times so
far, with a spinddown timeout of 10 minutes, and using laptop_mode), it
had a sata error:

And then it fails to reset after some time, remounting the devices
readonly (although what wasn't already in the cache became unreadable with
lots of IO errors rapidly filling up dmesg).  None of the logs made it to
disk, naturally enough, and this was what I caught in syslog before syslog
bailed.  There were interesting messages that happened after this, but the
dmesg buffer filled up before I thought about saving them.

My /sys/class/scsi_host/host0/link_power_management_policy is:
min_power
.  powertop had earlier (in a previous warm-boot) prompted me
to set link_power_management_policy, so I had been tweaking that, but I
didn't look at its default setting - I presume it was already at
min_power, as it is now from a fresh (cold) bootup.

Just in case it is related, in each bootup, I earlier get

and/or

[ 1587.842640] CE: hpet increasing min_delta_ns to 15000 nsec
(successively increasing as time goes on)

The sata link went belly up perhaps a few minutes after I went to bed
lastnight, and the only thing I can think of that I did before then was to
unplug and replug the ethernet and/or the wireless.  The ACPI messages
seem to happen around networking events on this laptop, but I haven't had
a chance to investigate further.

You must realize that the computer has it in for you.  The irrefutable
proof of this is that the computer always does what you tell it to do.
