What are the differences between the 2.4 and 2.6 Kernels?

[eqspec]

I am currently running 2.6.20 kernel, and I have had this issue for a long time now. It appeared when I upgarded for 2.4.27 to the 2.6 kernel. Currently the only distro that I know is running this kernel 2.4 is Debian Sarge, and I don't have the restart issue. I can revert back to Sarge at the expense of newer updates. But, for now I'm staying with 2.6 kernel. I just want to know if there is a major difference in ACPI or APM, between the two. Maybe I can build a custom kernel and try it.

Can you try booting up the 2.6 kernel and running the following

dmesg |grep -i acpi |tee ~/acpitest.log
sudo grep -ir acpi /var/log/* |tmp ~/acpitest2.log

Enter root password when prompted and post the contents of the the output files back here.

The second test says this "bash: tmp: command not found" . I can't sudo, I'm on PCLinuxOS, but I did become root on the second test. Thanks for the help.

Luking into the header for your query DIFFERENCE BETWEEN 2.6,2.4

major change in kernel is context switching time ,jiffies r made 1000 from 100 in 2.4 so instead of 10ms switch u will get interrupt 0x80 every 1ms

But this is no way related to your problem

1.Did u installed stable linux (U can get them from The Linux Kernel Archives)
2.U do make menuconfig or make xconfig to luk into your settings
3.when u do "make install" to get ur kernel to boot see ur not facing any problems
