There seem to be alternate ways of doing readahead, so I'm not yet
convinced it's worth the cost.  (It appears to add about 4-5K code and
static data, which is nothing on a PC but a bit more significant on an
ARM system with a fixed-size flash partition for the kernel image.)

Not that I can think of.  I know very little about IPMI.

Hi,

please consider enabling fanotify in the upcoming 2.6.37(-rcX) packages.

Systemd has a readahead implementation based on fanotify which we would
like to enable.

Thanks,
Michael

What we decided to do in Debian for the 'squeeze' release was to remove
these aliases from the modules.  An administrator can then re-add the
aliases in a local modprobe config file or add the modules to
/etc/modules.  (Or a userland support package may load the module, e.g.
decnet is loaded by dnet-common.)

I've now done this for af_802154, decnet, econet, rds and x25.

For future releases I intend to disable econet and possibly x25.  I also
proposed upstream to move decnet, econet and x25 into staging since they
have no regular maintainer, but this was NAK'd.

Ben.

I've been trying to reproduce it with linux 2.6.36 (+ the dbg
package), but I have gotten no problem. In fact, I have opened
rhythmbox and played a song while I play a video on youtube and then
try to suspend, which happens successfully.

I had tried kernel 2.6.36 and I had had the crash (without installing
the dbg package), but it happened less than with 2.6.32. I will keep
trying.

Coin,

Thanks for your investigation on the dmidecode part.

Quoting Ben Hutchings :


So, to use a cliché, have you tried turning it off and on again?


:-)
No, only reboots. I should be able to test this before X-mas.

Any other test i could do to help debug ?

Hi again,

I have been playing with git-bisect with the mainline kernel git
repository trying to pinpoint the cause of this problem and in the
process I noticed that I can't seem to be able to reproduce it
anymore, even with the official Debian 2.6.36 kernel that was causing
the problem before. Is it possible that some package upgrade on my
system (not a kernel one, obviously) has solved the problem? The
problem was intermittent from the beginning, but now I have
suspended/resumed many, many times without any problems.

Thank you,

Adriano

Re: ARM: OMAP2+ flavour

Pandaboard (OMAP4) and BeagleBoard (OMAP3) based devices boot off
SD/MMC card, in the case of Pandaboard it only boots off SD/MMC (no
MTD device available). debian-installer does not have support for MTD
devices due to parted not supporting it (#487738), but some
improvements have been done and bitrot [0]. So, basically, what
debian-installer needs to add to support such devices (taking in
account debian-installer runs native)? Maybe a cross installer which
puts together a kernel + rootfs in a cross way is more than enough. I
am currently cooking out one for my purposes (#604834), but it is not
ready yet. In anycase, if anyone takes the lead to add support for
OMAP into d-i and kernel, I am available to help and test it out.

Best regards
