hibernation fails on 6.9.5 ( on -current )
by Pigi_102 from LinuxQuestions.org on (#6NNT3)
Hi all.
Today I decided to give a try to a new kernel as I was on 6.1.10, running a ( quite ) old -current ( end of March 2024 ), because I was having some trouble on my new HP Elitebook.
I did the usual dance of a kernel compilation by using the .config provided in the kernel soruce package and booted into it without problems.
Everything seems to works fine, a part from the hibernation.
In the messages, after some time issueing hibernation I find a lot of
Code:un 20 21:02:26 topolinux kernel: PM: hibernation: hibernation entry
Jun 20 21:02:46 topolinux kernel: Filesystems sync: 0.006 seconds
Jun 20 21:02:46 topolinux kernel: Freezing user space processes
Jun 20 21:02:46 topolinux kernel: task:NetworkManager state:D stack:0 pid:1570 tgid:1570 ppid:1 flags:0x00004006
Jun 20 21:02:46 topolinux kernel: Call Trace:
Jun 20 21:02:46 topolinux kernel: <TASK>
Jun 20 21:02:46 topolinux kernel: __schedule+0x39f/0x15c0
Jun 20 21:02:46 topolinux kernel: schedule+0x26/0xf0and this is quite a long output of call trace and process that crash.
In syslog I get:
Code:Jun 20 21:02:46 topolinux kernel: Freezing user space processes failed after 20.006 seconds (18 tasks refusing to freeze, wq_busy=0):
Jun 20 21:02:46 topolinux e-hibernate[3631]: Failed to put system to sleep. System resumed again: Device or resource busyAfter that a lots of things starts to hang ( dmesg for example, but also reboot command) and the only way to get pc back is tu keep power button long pressed.
Rollbacking to my old 6.1.10 the hibernation ( and everything else ) comes back to working.
Now I'm compiling 6.6.34, wishing to get a newer kernel and in working conditions, but is there a chance anyone has an idea of why is happening ?
I'm reading the bissect document, but my english is far from let me understand correctly what I have to do.
I must say that I don't think is somewhat tied to -current, but I could be wrong.
Thanks in advance
