Comment 1 Andrew Morton 2007-10-14 11:16:02 UTC

Is this a regression from earlier kernels?  If so, what was
the latest kernel which worked OK?

Thanks.

Comment 2 Beno 2007-10-14 12:00:06 UTC

Yes it's a regression. 2.6.22.1 was OK. Do you want me to try 23-rc* ?

Comment 3 Rafael J. Wysocki 2007-10-14 12:42:55 UTC

Can you please attach your current .config?

Comment 4 Beno 2007-10-14 12:44:02 UTC

Created attachment 13155 [details]
config-2.6.23

Comment 5 Rafael J. Wysocki 2007-12-12 16:36:33 UTC

Please check the current mainline kernel and report back, thanks.

Comment 6 Roland Kletzing 2008-03-30 05:02:54 UTC

>Hello, whenever i suspend, the kernel clock is frozen.

Comment 7 Beno 2008-04-01 09:29:35 UTC
