BUG() in radix-tree.c, 2.6.11, reiserfs ?

[Stephane Jourdois <kwisatz@rubis.org>]

Hello all,

I was burning a DVD-R at 16x speed on IDE, the .iso was on /dev/sda1,
which is a reiserfs part on a SATA disk.  I was at the same time
building another .iso on /dev/sda1, with files from an lvm spawned on
/dev/sd{b,c,d}.

dvdrecord and mkisofs both finished, and the system froze hard
2 minutes later.


A similar problem has already been reported as seen in :
http://marc.theaimsgroup.com/?l=linux-kernel&m=111514360829643&w=4
This makes me feel it's a reiserfs problem, and as the other report
was on a p4 it is not specific to amd64...


The kernel comes with debian port for amd64, dunno much more.
It's a 2.6.11-9-amd64-k8.

I'll provide any information if requested (and if I can :-).


Thanks for reading,

Stephane.
