Computer fails to resume from suspend unless I rmmod jme before initiating the suspend

Computer fails to resume from suspend unless I rmmod jme before initiating the suspend

[Diego Viola]

Hi Guo,

I have an x86 computer with this network card:

02:00.0 Ethernet controller: JMicron Technology Corp. JMC260 PCI
Express Fast Ethernet Controller (rev 03)

Every time I initiate a suspend (systemctl suspend) the machine hangs
at resume unless I unload the jme driver.

Here is a Call Trace I was able to get after it hanged:

<IRQ>
tasklet_action+0xb0/0xd0
__do_softirq+0xcf/0x290
irq_exit+0xa3/0xb0
do_IRQ+0x54/0xd0
common_interrupt+0x82/0x82

<EOI>
jme_start_irq+0x84/0xa0 [jme]
jme_resume+0x12f/0x210 [jme]
pci_pm_resume+0x64/0xa0
? pci_pm_thaw+0x90/0x90
dpm_run_callback+0x4e/0x130
device_resume+0xd3/0x1f0
async_resume+0x1d/0x50
async_run_entry_fn+0x48/0x150
process_one_work+0x14b/0x440
worker_thread+0x48/0x4a0

? kthread_worker_fn+0x170/0x170
ret_from_fork+0x3f/0x70
? kthread_worker_fn+0x170/0x170

Please note that I had to type the calltrace above as I don't have a
serial cable and netconsole didn't work for me for some reason, so
there could be typos I didn't notice.

I run Arch Linux (x86-64), my uname is:

$ uname -a
Linux myhost 4.4.1-2-ARCH #1 SMP PREEMPT Wed Feb 3 13:12:33 UTC 2016
x86_64 GNU/Linux

Please let me know if you have any questions or need any other information.

Thanks,

Diego

I found something interesting, I can suspend/resume just fine when the
module is loaded and when I do this:

$ ip link set ens34 down

When I bring the device up again the hang still occurs.

I have tried to reproduce this problem with the latest git
(torvalds/linux.git) and also went back to Linux 3.11 and I still got
the hang with both, my plan was to run git bisect, but the problem
still occurs.

I opened this bug in bugzilla if it's preferred to deal with the problem there:

https://bugzilla.kernel.org/show_bug.cgi?id=112351

Thanks,
Diego

So I found that disabling async as in:

$ echo 0 > /sys/power/pm_async

Helps with my issue, I can't reproduce the hang anymore, tried
suspend/resume almost ~15 times.

Hi!

It seems to have some kind of suspend/resume support. ... and it is
rather complex.

Maybe jme_start_irq(jme) should be moved to the end of jme_resume
function?

Hi Pavel,

This did the trick, suspend/resume is now working perfectly for me
(tried more than 10 times). :)

Thank you so much, should I send a patch?

Re: Computer fails to resume from suspend unless I rmmod jme before initiating the suspend

[Guo-Fu Tseng]

Dear Diego and who concerns about this driver:

Thanks for reporting it. I can still provide some help, but it's just I'm quite busy.
So that you have not seem me sending patch for a long time.

I wrote this driver when I wan an intern in JMicron during one of my summer vacation
while I'm still student in 2008. And form that point, I do the maintenance just
for fun, not taking any money from them.

JMicron stopped contact me for a long time, and Diego told me that JMicron told him
this chip was EOL 6 years ago.

I have a confidential spec of this chip. I can still provide some help.

Diego is working closely with me for this issue right now.

Dear Guo,

I just wanted to say thank you for helping me fix the issues I had
with this driver. Thank you! You're awesome. :D
