Re: Fw: [lenzberger@xxxxxxxxx: [suse-security] SuSE 9.1 + quota = deadlock]

Hi,

sorry, i know that the information given by me was very poor.

i am running reiserfs and the device is listed in fstab this way:
/dev/hda2 / reiserfs acl,user_xattr,usrquota 1 1

i found some posts about this kind of problem when having acl
activated (even when not in use). but the strange thing is, that we
never had this problem on this machine before. i know, that users
reached their quota limit without problems. i think that it will have
to do with one of the last kernel upgrades on suse 9.1 (or maybe some
other packages?)

some information i found (maybe the same thing):
http://marc.theaimsgroup.com/?l=reiserfs&m=112170574830590&w=2

the first time we saw this bug on 2005-09-20 on our system. it does
not happen very often that our users reach their quota limit but now
we see that problem once or twice a week.

so it could be a problem since that update:
-rw-r--r-- 1 root root 9144 Sep 3 16:05 kernel-52369

any help would be fine - thank you.

christopher
