(1) One-line summary: I'm getting SATA timeouts with Intel 82801HB on amd64.

(2) Full description: Unless CONFIG_RCU_TORTURE_TEST is set, I get sata
timeouts of this form periodically:

ata1.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x2 frozen
ata1.00: cmd 60/18:00:b3:22:0a/00:00:00:00:00/40 tag 0 cdb 0x0 data 12288 in
res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata1: soft resetting port
ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata1.00: configured for UDMA/133
ata1: EH complete
SCSI device sda: 625142448 512-byte hdwr sectors (320073 MB)
sda: Write Protect is off
SCSI device sda: write cache: enabled, read cache: enabled, doesn't
support DPO or FUA

This entails complete blocking of all disk i/o (I only have one disk) for
about 45 seconds. The kernel then negotiates the next lowest transfer
speed (UDMA/166 all the way down to PIO0, when it errors saying it cannot
go slower). I get this issue on amd64 kernels only. The issue is only
present in 2.6.18+, since earlier kernels do not support my chipset at all
(intel 82801HB).

Knoppix 5.1.1 does not show this issue (i.e., no disk i/o issues even
without rcutorture running). However, a native amd64 build of exactly the
same kernel config shows the issue.

(3) Keywords: SATA, AHCI, modules, kernel, Intel.

(4) /proc/version: Linux delta 2.6.20 #15 SMP PREEMPT Sun Feb 4 20:25:02
EST 2007 x86_64 GNU/Linux.

(5) Most recent kernel version which did not have the bug: N/A

(6) Output of Oops.. message: N/A

(7) A small shell script or example program which triggers the problem:
simply logging in or accessing the disk in any way.

(8) Environment:

RCU_TORTURE_TEST enabled.
