The patches on that bug are not upstream yet the bug is marked as CODE_FIX. Could you please test 2.6.14 and see if the bug has been fixed another way? > The patches on that bug are not upstream yet the bug is marked as CODE_FIX. oh, I was only guessing what upstream means exactly. > Could you please test 2.6.14 and see if the bug has been fixed another way? OK, I tried vanilla 2.6.14_rc5, and it has the same behaviour (takes very long to boot, gdm takes 30s or more to display login screen, etc). Should I follow this up here, or at http://bugzilla.kernel.org/show_bug.cgi?id=5165 or both? Funny thing, it _seems_ to be 10x slower, but sound still plays ok, and typing on keyboard is still ok, but I don't know much about these things... will track upstream bug It can also be much slower. Doing this: dd if=/dev/urandom of=/dev/null bs=1M count=4 takes less than a second on my healthy system and about 43 seconds on the slowed-down one. I can also confirm the bug is still there with gentoo-sources-2.6.14-r2. Please change the resolution to something different than RESOLVED UPSTREAM (as it is *not*). Thanks, [a] I just installed vanilla-sources 2.6.15_rc1, and the "slowness" is still there. Aforementioned patches still work however. > Please change the resolution to something different than RESOLVED UPSTREAM (as it is *not*).

Well, if we were just watching vanilla kernel sources, than yes, you'd probably
be right. But since we're looking into gentoo-sources, which have their own
patchset, than I guess the patches fixing this error could go into
gentoo-sources as well. If they break swsuspend2 than it should be perhaps be
done via exclusive USE flags (fix my hyperthreading || have swsuspend working).
Still -- baffles the blimpers out of me, how such a *serious* bug could persist
in at least two releases of the kernel. Anybody listening out there?
[a]
I don't have a good knowledge of ACPI, and I don't have much clue about the implications of those patches. There may well be a reason that they are in the test tree and *not* yet in Linus' tree. Without being able to fully understand the patches, I won't add them to gentoo-sources until they are pushed to Linus' tree (which generally means they are fully expected to work). This is standard policy for gentoo-sources. Sorry for the inconvenience this bug is causing you, I expect it will be fixed soon... *** Bug 112604 has been marked as a duplicate of this bug. *** The bug I entered, 112604, was marked a duplicate of this bug. However in that bug, I state that using "top" or cat /proc/cpuinfo shows that the second processor IS NOT THERE. Has 2.6.13 changed so that an HT processor now only shows up as one processor? If you guy still see two processor in /proc/cpuinfo, please unmark that bug as a duplicate and reopen it. fixed upstream http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=4c0335526c95d90a1d958e0059f40a5745fc7c5d http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=6d93c64803a5fea84839789aae13290419c62d92 Fixed in genpatches-2.6.14-5 / gentoo-sources-2.6.14-r4 |
