Closing this bugreport, 2.6.23-grml and 2.6.23-grml64 are in a pretty good 
shape now and no core issues are left open.

Most important missing packages for grml64:

grml64-kerneladdons-2.6.23
truecrypt-2.6.23-grml64
virtualbox-ose-guest-modules-2.6.23-grml64

Current 2.6.23-grml works fine, we just need a recent build for grml64 
(including *all* external modules).

We should try to replace CONFIG_NR_CPUS=8 with something like CONFIG_NR_CPUS=16.

Update:

Notice: use gspca-source instead of spca5xx-source
Just uploaded drbd8, exmap, fglrx, ivtv, iscsitarget, ndiswrapper, openafs and 
truecrypt to grml-testing.

I don't want to support misdn (see #395244) and tidev anymore.

Update:

drbd8
exmap
fglrx
iscsitarget
ivtv (do we want to support it at all?)
misdn (do we want to support it at all?)
ndiswrapper
openafs
spca5xx
tidev (do we want to support it at all?)
truecrypt

Just finished initial version of 2.6.23-grml.

Missing modules:

drbd8
exmap
fglrx
iscsitarget
madwifi
misdn (do we want to support it at all?)
ndiswrapper
nvidia-kernel-legacy-96xx
openafs
tidev (do we want to support it at all?)
truecrypt
tp-smapi

2.6.23 is available

Integrate http://dev.gentoo.org/~spock/projects/uvesafb/ and http://
mjanusz.wordpress.com/2007/08/29/fbsplash-naming-changes/ in grml?

Use Ubuntus' libata/pata-configuration?

try building with CONFIG_BLK_DEV_LOOP=m instead of y so we can test whether 
integration of loop-aes is possible. live-initramfs might handle that already 
for use....

activate CONFIG_NFS_V3_ACL

CONFIG_IRQBALANCE?

CONFIG_TASKSTATS -> CONFIG_TASK_IO_ACCOUNTING -> would be nice for 'dstat -M 
topio'

enable CONFIG_UTS_NS?

Activate CONFIG_PERFMON?

JFTR: I'd *like* to base grml 1.1 on kernel 2.6.23, let's see when it's 
available.

Include:

CONFIG_SERIAL_8250_NR_UARTS=16
CONFIG_SERIAL_8250_RUNTIME_UARTS=8

-> http://permalink.gmane.org/gmane.linux.distributions.grml.user/1336

deactivate CONFIG_DEBUG_MUTEXES

activate CONFIG_BLK_DEV_IO_TRAC?

additional notes:

switched from spca5xx-source to gspca-source, see

workaround for spca5xx-source and misdn-kernel-source:

touch /usr/src/linux/include/linux/config.h

workaround for exmap-modules-source:

ln -s /raid/Grml/kernel/linux-2.6.22-grml /lib/modules/2.6.22-grml/build

Removing et131x-modules-2.6.22-grml because of unsolved:

# depmod -ae -F /boot/System.map-2.6.22-grml 2.6.22-grml
WARNING: /lib/modules/2.6.22-grml/extra/et131x.ko needs unknown symbol 
vlan_group_set_device
WARNING: /lib/modules/2.6.22-grml/extra/et131x.ko needs unknown symbol 
malloc_sizes

fixed the r1000 issue with replacing pci_module_init() with 
pci_register_driver()

JFTR: we already have CONFIG_CFG80211=m set

Some furthe investigation needed in:

# depmod -ae -F /boot/System.map-2.6.22-grml 2.6.22-grml

WARNING: /lib/modules/2.6.22-grml/misc/r1000.ko needs unknown symbol 
pci_module_init

update: the 'WARNING: /lib/modules/2.6.22-grml/misc/pcan.ko needs unknown 
symbol malloc_sizes' problems of grml-kerneladdons-2.6.22-grml should be fixed 
now.

btsco -> use plugz instead -> http://bluetooth-alsa.sourceforge.net/build.html

check out situation of iteraid.ko (do not forget it in initrd/scsi/modules/)

We should include CONFIG_CFG80211=m in the next build.

Check out status of http://bugs.debian.org/425356 ->

iwlwifi -- The iwlwifi project provides a driver which utilizes the new 
mac80211 subsystem for the Intel® PRO/Wireless 3945ABG Network Connection 
adapter.

Another check to be done: in-kernel vs. out-of-tree kvm

JFYI: Just uploaded the first build to http://dufo.tugraz.at/~prokop/grml-
kernel/2.6.22-grml/

JFTR: gcc 4.2 (4.2-20070707-1) does not work for compiling 2.6.22 here yet:

regarding CONFIG_IRQBALANCE: use irqbalance (userspace) instead

Set CONFIG_SERIAL_8250_RN_UARTS to '16', see
http://lists.debian.org/debian-kernel/2006/07/msg00266.html

Work in progress: http://dufo.tugraz.at/~prokop/grml-kernel/2.6.21-grml/

TODO:

* Disable CONFIG_IRQBALANCE?
* External modules (defered currently until stable release is available)
