I'm experiencing the same issues with AHCI configured.
Running the Intel DG43NB with this JMicron controller card onboard ..:
{{{
$ lspci | grep JMicron
02:00.0 IDE interface: JMicron Technologies, Inc. JMB368 IDE controller
}}}
Running this kernel:
{{{
$ uname -a
Linux ubuntu-computer 2.6.24-23-server #1 SMP Mon Jan 26 00:55:21 UTC 2009 i686
GNU/Linux
}}}
When a HDD is plugged in:
{{{
ata4: irq_stat 0x000000040, connection status changed
ata4: SError: { DevExch }
ata4: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xa frozen
ata4: irq_stat 0x000000040, connection status changed
ata4: SError: {CommWake DevExch }
ata4: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xa frozen
}}}
... and repeat, over and over again.
If I remove the HDD drive, the errors stop.
Trying to configure the SATA controller as "Native IDE" ... no SATA
drives are detected.

How can I go about trying a newer kernel?
