Weird kernel oops

http://forums.fedoraforum.org – Just installed Fedora 12 on my new Acer Aspire 1410 this morning. And it almost works out of the box (boring.. but whatever). But I'm having some problems.. After some time it seems that NetworkManager is crashing (losing wireless connectiong and not being able to start it again), and syslog spits out the following in any terminal: Quote: Message from syslogd@localhost at Jan 17 21:09:29 ... kernel:Oops: 0000 [#1] SMP Message from syslogd@localhost at Jan 17 21:09:29 ... kernel:last sysfs file: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT1/uevent Message from syslogd@localhost at Jan 17 21:09:29 ... kernel:Process phy0 (pid: 505, ti=f65fc000 task=f408f2c0 task.ti=f65fc000) Message from syslogd@localhost at Jan 17 21:09:29 ... kernel:Stack: Message from syslogd@localhost at Jan 17 21:09:29 ... kernel:Call Trace: Message from syslogd@localhost at Jan 17 21:09:29 ... kernel:Code: 10 89 4c 90 08 42 83 fa 0e 89 10 75 05 e8 1b fe ff ff 89 d8 50 9d 8d 74 26 00 5b 5d c3 55 89 e5 57 56 53 83 ec 04 0f 1f 44 00 00 <66> f7 00 00 c0 89 c3 74 07 e8 48 f9 ff ff eb 52 3e ff 48 04 0f Message from syslogd@localhost at Jan 17 21:09:29 ... kernel:EIP: [<c049b613>] put_page+0xe/0x76 SS:ESP 0068:f65fde34 Message from syslogd@localhost at Jan 17 21:09:29 ... kernel:CR2: 000000001c808014 A couple of second later all terminals are also made useless.. I can open gnome-terminal and xterm.. but I am not able to write anything, like if my keyboard didn't work.. (but it does since I am able to use it in other programs). I have tried 4 other distros on this laptop in the last couple of days (Ubuntu, Puppy, Arch and Debian) without running into a similar problem, so I guess it's something about the kernel shipped with Fedora.. BTW.. I had to put "intel_iommu=off" in GRUB's menu.lst to make the kernel boot to begin with.. Maybe it has something to do with that? (didn't have to do that in the other distros either) ---------- Post added at 10:35 PM CST ---------- Previous post was at 10:29 PM CST ---------- Hm... Something tells me that I've just fixed the problem.. Removed the intel_iommu=off from menu.lst.. And it still boots.. (I had the intel_iommu=off problem with the kernel shipped with fedora 12 .. the new one that came with the update manager doesn't seem to need the line anymore) I'll just wait a day and see if it actually works now.. So... 2.6.31.5 needed the intel_iommu to be off.. and 2.6.31.9 doesn't.. Thanks for reading anyway. (HowTos)
