Kernel log oddities in boot log (2).
![](https://seccdn.libravatar.org/avatar/d74fe80cdf7be80d213fb7e19730ea2d.jpg?s=120&d=mm&r=g)
Here are some oddities that I have spotted in the kernel log, in my boot log. I am using SuSE 7.3 Pro on a box with an Award BIOS/Soyo Dragon Plus! motherboard. The first is regarding APIC, which is why I recompiled the kernel, i.e. I wanted to get the computer to shutdown when I tell SuSE to shutdown: <4>Local APIC disabled by BIOS -- reenabling. <4>Found and enabled local APIC! Another thing with APIC is: BOOT_FILE=/boot/vmlinuz enableapic vga=0x0317 disableapic ide=nodma apm=off Why enable apic and then disable apic and the reverse above? The second odditiy is more worrying seen with my eyes (or is it just me???): <4>FAT: bogus logical sector size 5376 <4>FAT: bogus logical sector size 5376 Any ideas from the list? Cheers, Brian

Well, I'm not sure of WHY , but I have the same messages, and run without problems. I think APIC is important for assigning shared pci irqs. It's better to let linux handle it, than the bios. So people have recommended to disable it in bios. The FAT message is probably some obscure reference to the differences between linux mkdosfs and windows fdisk. -- $|=1;while(1){print pack("h*",'75861647f302d4560275f6272797f3');sleep(1); for(1..16){for(8,32,8,7){print chr($_);}select(undef,undef,undef,.05);}}

This I understand and while I am not too thrilled about the idea, as I am using a dual boot system (SuSE and Win 2K), I would do it. However, that option is not available to me in my BIOS. Therefore, I must try to get SuSE to work with the BIOS and not against it or whatever it is doing. That is why I recompiled the kernel for APIC support: In General Setup Power management ACPI Support set Y ACPI Bus management set Y System set Y Processor set Y There is one more step that needs to be done, when I get enough courage together to try compiling the kernel again: CONFIG_APM_REAL_MODE_POWER_OFF So I guess that the above message isn't anything to worry about? Any other comments from the list on the issue? Cheers, Brian

Aren't ACPI and APIC different things? There should be some archived discussion about this from a couple of months back. I just run with a 'disable apic' option, never noticed any probs. HTH Fergus

Sorry, that was a typo. I am talking about ACPI. Cheers, Brian
