I see two worrying lines in the log.
Firts, the last one:
Code:
Sep 1 15:45:55 TomHPdv7 udevd[1817]: could not find module by name='rtc_cmos'
I suppose that you are running Slackware -current as you are using a 3.2.28 kernel.
This is supposed to be fixed since RC3:
Code:
a/udev-182-i486-4.txz: Rebuilt.
Commented out the entries in /lib/modprobe.d/isapnp.conf to fix
the error attempting to load rtc_cmos. Thanks to GazL.
Is your Slackware properly uopgraded?
Alse, check the content of /etc/modrobe.d. There should be only two files in it now: README and (possibly) blacklist.nouveau.conf.
If they are others, just remove it. Noticeably, remove isapnp.conf.
Second, this one:
Code:
[drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call failed
I don't know if that caused the freeze but I suggest you investigate from there as a Google search on that returns a lot of results.
Anyhow, I see no reason to assume that your problem be kernel related, so I suggest you post it in the Slackware forum instead to get more useful answers (or click the Report button and request a moderator to move the thread there).
