Problem with ata layer in 2.6.24

Hello

After my upgrade to CentOS5.1 and ART, thank you for all your hard work. My server started hanging every couple of days. Decided to try the acpi=off using the grub.conf.

I tried the setting acpi=off. I used the following setting in my grub.conf

Code:

title CentOS (2.6.23.1-3.art)
   root (hd0,0)
   kernel /vmlinuz-2.6.23.1-3.art ro root=/dev/md0 console=tty0 console=ttyS0,57600n8 acpi=off
   initrd /initrd-2.6.23.1-3.art.img

When I booted from the ART kernel I get the following error:

Code:

Starting postgresql service... 
 not installed
Starting psa-spamassassin service...                                 done
Starting Plesk... ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

When I rebooted a different process started causing the same error and kept repeating its self on the serial terminal, when I booted into the standard CentOS 5 Kernel with no acpi=off, no errors!

Been up two days now almost 3

Also is it safe to enable the Plesk Firewall with ASL, becuase I have disabled access to SSH ports using 1and1s firewall and im still getting DenyHosts Reports.

Any help with this would be greatly appreciated, so I can be nice a secure server.

The 2.6.24.x ASL kernel is in the works, Ive had some reports by other people of odd hangs that we've never been able to investigate (could have been a shun). This is a good thread to keep track of, so it could all be related. Thanks for the heads up.

And yes, its safe (and encouraged) to use some firewall interface with ASL, it should work just fine with PSA's, APF, firestarter, etc.
