The major problem is, the idle task queue status depends on where there is other task in the rq. I'm not sure if it is the cause of the frozen issue, but this is totally wrong. So, no matter how rare the issue can be triggered, it must be undone.<br />I'm preparing the revert patch and make a new PDS release this weekend.<br />Thanks all for testing and provide the feedback.Alfred Chenhttps://www.blogger.com/profile/03164306846702841944noreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-11411016208850851022018-08-28T20:03:16.157-07:002018-08-28T20:03:16.157-07:00@sysitos

No more tests. I only tested to reach that freeze with different versions during git bisect and than checked another commit. With newer commits, the freeze seems to be occur more quicker. Most time, the freeze comes right after login, during network manager tries to connect to my wlan. (had in mind, that this was the cause, but with normal LAN connection there is a freeze too) Sometimes the freeze comes later during normal work (e.h. in firefox or console - no high load). Some freezes come after s2ram, and 1 during s2ram. All are hard freezes, only power button does help. With commit 1e72b40cf0605fe09aca0442c2644d4b9228ffc1 the working without freeze was longest, so the first time I assumed, that there was no problem with this commit. But I can check if there is a freeze with normal work too on this commit.<br /><br />Regards sysitos<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2963790426029213933.post-18455251326677419782018-08-28T16:11:14.762-07:002018-08-28T16:11:14.762-07:00@sysitos
