This email lists some known regressions in Linus' tree compared to 2.6.20.

If you find your name in the Cc header, you are either submitter of one
of the bugs, maintainer of an affectected subsystem or driver, a patch
of you caused a breakage or I'm considering you in any other way
possibly involved with one or more of these issues.

Due to the huge amount of recipients, please trim the Cc when answering.

Hello,

This one is a small issue, I got bigger ones: as I said change in code order in suspend code broke both suspend to ram and disk

Those are commits.
Â Â Â Â Â Â Â Â e3c7db621bed4afb8e231cb005057f2feb5db557 - [PATCH] [PATCH] PM: Change code ordering in main.c (breaks Â S3)
Â Â Â Â Â Â Â Â ed746e3b18f4df18afa3763155972c5835f284c5 - [PATCH] [PATCH] swsusp: Change code ordering in disk.c (breaks swsusp, I don't use it, but I tested it)
Â Â Â Â 259130526c267550bc365d3015917d90667732f1 - [PATCH] [PATCH] swsusp: Change code ordering in user.c (breaks uswsusp, that I use)

System freezes before suspend with those commits, even before suspend to disk.

I think that is is not so good idea to tell about all bugs in single letter ;-)

Regards,
Maxim Levitsky

This was in my list as

Subject : suspend to disk hangs
References : http://lkml.org/lkml/2007/3/16/126
Submitter : Maxim Levitsky <maximlevitsky@gmail.com>
Status : unknown

But I should add your bisecting information there.

These were 6 emails.

And they should give an overview as complete as possible of all
currently known regressions.

You didn't understand me, I wanted to say that I sent a email with subject line
"[BUG] 2.6.21-rc1,2,3 regressions on my system that I found so far"

And I think now that I did wrong that I put all regressions and bugs I found here, but not in separate emails
Anyway it is not a problem

And by the way suspend to ram also hangs and hangs before suspend (Disk powers down, screen too, but fans are on, and etc...)
Reverting those fixes it.
