N-inode-attrs.patch uses previously unused field in reiserfs on-disk
inode structure to store inode attributes. It seems that in some cases
this field actually contains garbage. It may happen that you have got
immutable bit for your console device this way.

As a work around try to boot with ext2, do

lsattr /dev/console to check, and run 

chattr -R -SAadiscu /reiserfs-mount-point

for each reiserfs file system to clear all attributes. Yes, it's silly.

Apart from the above problems with the new N-inode-attrs.patch
2.4.15-pre7 + preempt + ReiserFS patches A-M flies.

Thanks Andrea, Linus and the whole ReiserFS team.

BTW If only the little MP3 playback (Noatun, KDE-2.2.2) hiccup after 9-10 
seconds of the dbench test would disappear. I think we need IO reservation or 
priority, no?

BTW2 Dear ReiserFS team have you read the thread about ACLs/extended file 
attributes on LKML lately?

OK, I've found it.

N-inode-attrs.patch (both versions) is broken. After I've backed it out 
2.4.15-pre7 + preempt + ReiserFS A-M is up and running.

My .config is the same like the one for 2.4.15-pre6-preempt. So, yes, like 
I've did it for ages...;-)

Thanks,

PS I am fiddling around with the other new ReiserFS patches, now.

Sure you compiled in Virtual Console support, or Serial Console support?

Sorry Nikita,

but kernel 2.4.15-pre7 + preempt + ReiserFS A-N do _NOT_ boot for me.
I've tried it with "old" and "new" (current) N-inode-attrs.patch. But that doesn't matter.
