Re: SMART problems in 2.6.22

Hi Jeff,

It's possible that the recent addition of ACPI support will cause disks to be in different modes than previously expected. ACPI supplies ATA taskfiles to be pushed to the disk, and who knows what's in there...

Is there a simple way I can have affected users test this? Is there a kernel boot flag or sysctl setting or something else they can use to disable the ACPI stuff so see if the problem then goes away?

The 'noacpi' module option.

OK, thanks.

Klaus, Jan: could you please see if your problem with 2.6.22 goes away with noacpi passed as a flag to libata?

Jeff: I will add the noacpi test suggestion into the Debian bug report here http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=428975 to try to ensure that Klaus sees it.

Cheers,
Bruce
