Bug Description

Binary package hint: hal

Ubuntu version: 9.04 Jaunty Jackalope amd64
Package version: 0.5.12~rc1+git20090120-0ubuntu1

hald segfaults on vanilla kernel 2.6.29-rc2 and -rc3 (-rc1 not tested) with the following kernel error:
hald[2957]: segfault at 80 ip 000000000042f63b sp 00007fff635a57e0 error 4 in hald[400000+57000]

After a manual restart of hal it works as expected.

If you need further information please let me know.

I further examined this problem. It's related to this reported regression on lkml:
http://marc.info/?t=123139972800002&r=1&w=2

As a consequence, if CONFIG_MMC is disabled in 2.6.29-rc3, the problem vanishs and jaunty boots correctly.

I was going to apply the patch that fixes this from the current GIT tree, but I noticed we're already running a GIT snapshot of HAL, so I just did another snapshot (which has the fix for this)

It still had the (quite large) .git folder

Thanks a lot Chris! I merged your branch into the ubuntu branch and prepared the package for upload. However, I'll wait with that until Alpha-4 gets released tomorrow (soft freeze ATM).
