Hi,

I get a hanging SATA port for a few seconds during boot, with these
kernel messages:

ata1.00: exception Emask 0x0 SAct 0x3 SErr 0x40000 action 0x6 frozen
ata1.00: cmd 60/20:00:55:e1:65/00:00:00:00:00/40 tag 0 ncq 16384 in

This happens with 2.6.39-rc6 with TuxOnIce patch included, but during boot
without any suspend actions. The hardware is a ThinkPad X61s:

00:1f.2 SATA controller: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E)
SATA AHCI Controller (rev 03)

Complete dmesg is attached.

Regards,
Tino
