Kernel 3.16.0-21-exton (Kernel.orgs stable kernel 3.16.4)

Posted 10-06-2014 at 05:33 PM by exton (Exton's Blog)

I have compiled yet another Ubuntu/Debian kernel for 64 bit systems. This time kernel 3.16.0-21-exton, equivalent to Kernel.orgs stable kernel 3.16.4, released yesterday (141005). It is not yet possible to compile kernel 3.17 (also released 141005) for Ubuntu systems.

Liquorix kernel seems more responsive than Debian's default

Posted 05-28-2014 at 11:46 AM by the dsc (linux-related notes)

I'm somewhat skeptical of the tuned-kernel movement, so I didn't install it expecting to make my OS "fly" or anything. It just happened that recently there had been some weird kernel error messages ("perf samples too long"), and, related to that or not, the OS would become sluggish with lots of read-or-write activity (on my old HDD that must be really slow, to add to sluggishness). Apparently you can sort of solve it in a sysctl-like way, printing a "0" to some file/parameter,...

Mapping address to line - Linux

Posted 08-31-2011 at 01:20 AM by hi2arun
Tags debug, kernel, panic

Well.. when you write your own kernel module, in the devel stage, chances for bringin down the kernel (panic.. ah sick) are huge.
Oops (pet name for kernel panic) mostly spits lots of martian traces that include stack addresses, registers and its value, EIP, etc.

To know the culprit line that caused panic, decode the address to line as follows:
EIP wud luk like...
Code:
EIP: [] ip_check+0x45a/0x21a [ip_tables] SS:ESP 0049:c098281a
Look at the selection...
