jnl: unknown-dev: journal start/end pointers reset!


4 posts in this topic

Recommended Posts



I'm new to this forum and I already had a lot of fun with mac os x leopard on a regular pc.


First I downloaded the Kalyway 10.5.2 disc but just a second after the darwin x86 bootloader appeard my computer spontaniously rebooted, It didn't matter wich kernel or mode I used.


So I downloaded the iATKOS1.0ir2 CD and evrything seemed to go great, I passed the installation and I rebooted into windows. With the help of this guide I managed to dualboot using tboot.


So I restarted into mac os x, the darwin x86 bootloader appeard and my computer spontaniously restarted. In "-v" mode I saw that it had something to so with the AppleIntelCPUPowerManagement extention. So I deleted AppleIntelCPUPowerManagement.kext using tmac on windows and I rebooted.


It had much effect, now it takes much more time before my computer restarts.


In "-v" I saw that the last line it says before my computer restarts is

"jnl: unknown-dev: journal start/end pointers reset! (jnl 0x3f80f00; s 0x476600 e 0x476600)"


System specs:

Intel pentium 4 (SSE2)

NVIDEA gforce mx 400

2 harddisks one for windows xp and oe wich is splitted in to 2 partitions, 1 for xp and one for mac os x they are both IDE.

512mb of ram.


Is there anyone who knows a solution?


Sorry for my poor english and grtz,

Had kind of the same problem. Thems to be an filesystem error, so I checked the filesystem in single user mode:


Start in single user mode with option -s at the startup

Type into prompt: /sbin/fsck -fy


The command checked the filesystem for on my startup volume and mith an reboot command I restarted the computer. Then it booted up into the OS.


In my case I didnt shutdown the OS correctly, so it got some errors on the filesystem while I just had to turn off my computer...


Hope this will help anyone
