When booting on my laptop (with 2.6.24 kernel from ubuntu hardy) I get:

ACPI: \_SB_.PCI0.IDE0.SECN.BAY1: found ejectable bay
ACPI: \_SB_.PCI0.IDE0.SECN.BAY1: Adding notify handler
ACPI: Error installing bay notify handler
ACPI: Bay [\_SB_.PCI0.IDE0.SECN.BAY1] Added

please attach the output from acpidump.

Did you see these warnings with earlier releases (say, 2.6.23)
or did they just start in 2.6.24?  do you still see them
with a kernel.org kernel?

BTW, this doesn't look so good -- have you always seen these?

Hi, Laurent
The dmesg in comment #7 doesn't show the error message.
Will you please enable the debug of ACPI in kenrel configuration and attach the dmesg ?
Thanks.

Thanks for the log.
Now it is enough.
Comment 12 ykzhao 2008-03-06 22:05:21 UTC
Hi, Kristen
    From the log in comment #10 and #7 it seems that this bug is related with bay driver.
    In this laptop the bay1 device is located in _SB_.PCI0.IDE0.SECN. And ATA driver will install the notify handler for this ACPI device from the kernel of 2.6.24.(The main reason is that libata_noacpi is zero and ata will be assocatied with ACPI). So when bay driver install the notify handler for this device, the following message will be reported. 
>   Error installing bay notify handler
    
    Will you please take some time to look at this?
    Thanks.
   
Comment 13 Shaohua 2008-05-05 22:37:50 UTC
libata-acpi can handle bay well. I thought we could remove bay driver.

debug patch

please try latest kernel with attached patch and not select acpi bay driver, and check if your bay eject works. if it works, I'll remove bay driver.
Comment 15 Shaohua 2008-06-17 20:00:11 UTC
This issue is already fixed in latest kernel. mark this closed.
