This looks related or possibly a dup of bug 754075 I think related. This one involves rtl8192se, and the other rtl8192se; however, both use rtlwifi, and the problem may be there. Please try the following (as root): modprobe -rv rtl8192se modprobe -v rtl8192se ips=0 The above will disable power save in the interface, which seems to be indicated. Does it help? I think related. This one involves rtl8192se, and the other rtl8192ce; however, both use rtlwifi, and the problem may be there. Please try the following (as root): modprobe -rv rtl8192se modprobe -v rtl8192se ips=0 The above will disable power save in the interface, which seems to be indicated. Does it help? The system freeze has quite an irregular pattern, I have seen it hang 2-4 hrs after reboot. I haven't experienced a freeze till now after 4-6 hours after executing the above command. Will report if the freeze happens again. Also, I have seen it happen more often when I resume from sleep than actually a fresh restart. That makes sense. I never see this fault with rtl8192ce, rtl8192se, or rtl8192de, but I never put my machine to sleep - that feature does not work here. Thanks for testing. So, there is no support for sleep/resume. What should an end user do in this case ? I did not say that. What I cannot do is test, not because of problems with rtl8192ce, but with another component. If you want sleep/resume, you need to test. I will support any problems that you find, but I cannot find them for you. BTW, hibernate works. OK, I will be happy to test. I don't get messages like the one above now, but the system still freezes producing no output in /var/log/messages What should be the next step ? I tried the ips=0 option, I can't say exactly whether it had an affect or not. It still froze but I guess it ran longer. If you do not see messages like the one above, then you have a different problem. Note, if you have to power off the system to recover, anything logged will be lost. When you get a freeze, does the system recover in 30 seconds, or so? If you switch to the debug console (CTRL-ALT-F10 on my openSUSE KDE system), is anything logged to the screen? Do you see a kernel panic (keyboard lights flashing once per second)? If you do not see messages like the one above, then you have a different problem.

I don't see the above messages now, I was getting them earlier. I have to do a hard reboot all the time, the system becomes completely unresponsive. ctrl-alt-f2- (fedora) doesn't work. No key combination works. The system restart takes the normal amount of time as it does ~50 secs or so. No, I don't see a kernel panic (flashing caps lock light).

I've enables the test updates repository but this update doesn't come up Should I just wait a few more days? (In reply to comment #20) > Stansliaw, what do you want for Christmas?
