Kernel 2.6.20-13 On AMD64
Kernel 2.6.20-13 introduced strange behaviour with respect to nvidia drivers, causing the system not to boot. Reverting to drivers prior to -13 was working perfectly.
Kernel 2.6.20-15 fixes this.
From dmesg / /var/log/messages:
Apr 13 18:58:28 localhost kernel: [ 49.943586] **WARNING** I2C adapter driver [NVIDIA i2c adapter 0 at 7:00.0] forgot to specify physical device; fix it!
Apr 13 18:58:28 localhost kernel: [ 49.943634] **WARNING** I2C adapter driver [NVIDIA i2c adapter 1 at 7:00.0] forgot to specify physical device; fix it!
Apr 13 18:58:28 localhost kernel: [ 49.943655] **WARNING** I2C adapter driver [NVIDIA i2c adapter 2 at 7:00.0] forgot to specify physical device; fix it!
From -15 dmesg still reads the same message, but it is now harmless. Supposedly nvidia is working on this in their new driver release.
Modified partition table, now / is on a different partition
/etc/fstab uses UUIDs in Ubuntu Linux. You can find out your UUIDs by:
ls /dev/disk/by-uuid/
To obtain the UUID of a disk not in your list (the ‘new’ partition), do:
vol_id -u /dev/
Be sure to update /boot/grub/menu.lst to reflect these changes, otherwise your system will not boot, causing Error 22 on startup. Don’t dispair, Damn Small Linux can help you out.
A generic Bash / Linux commandline article. Some handy stuff mainly for reference.
AWK is a very powerful scripting language. It can really help you get stuff done. An example is the parsing of the output files of simulation software and deriving summaries, averages, confidence intervals and the like.
