ata_piix init/performance regression ?

Hello !

on my old fujitsu-siemens lifebook, booting is at least 20 seconds slower as before.

on ata_piix init i can see 2 longer delays of ~10 seconds each, which didn`t happen before.

i`m using SuSE kernel of the day from http://ftp.suse.com/pub/projects/kernel/kotd/

problem exists with these kernels:
kernel-vanilla-2.6.24_rc3_git3-20071201095839
kernel-default-2.6.24_rc3_git3-20071201095839
kernel-default-2.6.24_rc4_git3-20071206172629
kernel-vanilla-2.6.24_rc4_git3-20071206172629

problem didn`t exist with this one:
kernel-default-2.6.22.12-0.1 (opensuse 10.3 default)

please see https://bugzilla.novell.com/show_bug.cgi?id=345442 for more details.

regards
roland

That's a TSC problem on suse kernel. I'll follow up on the bugzilla.
