Colonel Badger Posted February 18, 2008 Share Posted February 18, 2008 Using IAtkos 1.0ir2 on my platform. Have been trying to get speedstep working so I needed a speedstep enabled SSE2 kernel. Downloaded the 10.5.2 (9.2.0) kernel from NetKas and installed it. Works like a charm with speedstep.app, AppleACPICPUThrottle.kext etc. However I started noticing that almost always when I boot the machine on battery it kernel panics before I get the GUI. On A/C it works perfectly. I removed the speedstep stuff to see if it was the culprit but it still panics. Says something like: "BSD Process name corresponding to current thread: fsck" Which I presume means it panicked in fsck. I don't have a panic log anywhere and can't seem to find the reference to the boot panic in my system.log so I can't give you the verbose panic line. Anybody else see this? NetKas if you're online, do you know what might be causing this? NB: I've only updated the kernel to 10.5.2, I HAVE NOT updated the rest of the OS, since I want everybody else to iron out the issues before potentially wrecking my (almost) perfect 10.5.1 install. Could this be the issue? HELP!! So close to having this work perfectly, the only thing I can't do is boot on battery right now. Thanks Mark.

Colonel Badger Posted February 18, 2008 Author Share Posted February 18, 2008 Bump. Anybody seen this before?

00diabolic Posted April 17, 2008 Share Posted April 17, 2008 I dont have exactly this problem on my 10.5.2 install but its simular. With 10.5.1 I had no issues with power mangement, on battery or AC. With 10.5.2 I have almost perfection on AC speedstep.app loads with 9.2 SS kernel, USB unplug and plug in fine most of the time, performance is fine (the system says is still says its battery, but I guess that is common). On battery though its an absolute flipflop. Speedstep.app goes away and wont come back, USB devices wont show up and system slows down a lot. It gets so slow that it takes something like freakin 10 mins to shutdown. Is this powermgmt related or more kernel? Wish I knew. I have come a long of way with 10.5.2 and solved a lot of problems. I plan to solve this one but there are not many people with issues like this one so I might be SOL.

FurmanSK Posted April 17, 2008 Share Posted April 17, 2008 Yeah me and another guy have the same problem with our laptops. Was at school today and was going to test some wireless drivers on the mac and i forgot my AC cord and couldn't boot because of this. Really pissed me off because I've done the powermanagement.kext hack and fixed that but for some reason still won't load. Running 10.5.2 IBM Thinkpad T43 Hopefully this will get popular and get fixed Link to comment https://www.insanelymac.com/forum/topic/88423-kernel-panic-using-netkas-1052-universal-kernel-on-battery-only-fine-on-ac/#findComment-713373 Share on other sites More sharing options...
fdboy Posted June 3, 2008 Share Posted June 3, 2008 This also happens to my two sse2 only laptops with netkas 9.2.0 kernel: one got kernel panic on battery, another one can boot, but extremely slow. Temporary solutions for me 1) has to boot on AC, once booted, one can detach the ac adaptor. 2) I have dual-systems: I firstly boot into windows, then do a hot restart, then boot into leo. This works for me even with on battery only. Hope 2) will also work for you. It's a strange problem, hope somebody can fix it eventually.

Ultimatebadass Posted June 5, 2008 Share Posted June 5, 2008 I have exactly the same problem on my AMD ASUS Z92Km(A6Km) laptop. Everyting works fine when booting from A/C power but on battery, depending on the Leo/Tiger "distro" I've tried there are various symptoms: a ) won't boot at all -> kernel panic with fsck b ) won't boot at all -> stops somewhere along the way and stays there c ) boots, but the UI is VERY slow, like 5 times slower than usual, clock doesn't show up Right now i'm using Kalyway 10.5.2 AMD/Intel with the modbin kernel and this one behaves like "c". I found this thread: http://forum.insanelymac.com/index.php?showtopic=99891 and tried to mess around with the APIC kernel flags, since I figured that might have something to do with those "timer" flags but nothing seems to work Link to comment https://www.insanelymac.com/forum/topic/88423-kernel-panic-using-netkas-1052-universal-kernel-on-battery-only-fine-on-ac/#findComment-771743 Share on other sites More sharing options...
Beaubarre Posted July 27, 2008 Share Posted July 27, 2008 Hello, Just try to disable speedstep in the bios setting worked fine for my thinkpad X40 best regards Link to comment https://www.insanelymac.com/forum/topic/88423-kernel-panic-using-netkas-1052-universal-kernel-on-battery-only-fine-on-ac/#findComment-835133 Share on other sites More sharing options...
moridinbg Posted November 18, 2008 Share Posted November 18, 2008 This happens to me too. On AC it bots nicely, but on battery it's impossible. I had the fsck panic issue at several occasions, which seems to be fixed by -x boot flag. My bad. It still panics. Is there a solution different than disabling SpeedStep? Wouldn't that seriously affect the battery life?

squeezebag Posted March 24, 2009 Share Posted March 24, 2009 Any resolution on this? I'd like to turn off speedstep in the bios on MY x40 thinkpad, but I don't know how it's possible. Any helpful hints? Update: Sorry. I feel like a dickhead but I just didn't look hard enough at my bios screens. If I had just cursor-ed down on the power screen I would have seen it there. Change the speedstep battery profile from maximum battery to automatic and problem is fixed.
