but when I read that DVD on the original machine, the system is stuck,

when I read the same DVD on the second machine, where I wrote it,

Fact: I can write a DVD on a machine with kernel-2.6.11, but I cannot

I can't explain but we may try to fix it with your help.

As a general remark, dmesg + .config + lspci -vx/lsmod help figuring the
hardware environment.

1 - can the regression be reproduced with last -rc (namely 2.6.13-rc4) ?
2 - if yes, can you isolate a simple operation to trigger the bug: I assume
    you read the DVD from hell with some nice viewer under X. Can you
    reproduce the bug in a simple console, without X, through a 'dd'
    command for instance ?
3 - if so, did you notice extra messages ? Is led activity available ?
4 - if you are still stuck, you can start a binary search on the 2.6.12-rc
    kernels, then on the 2.6.12-rcX-gitY to isolate the trigger (it may not
    necessarily be the culprit).

2.6.12? It looks more like your "original"/tico machine uses a 2.6.8.

I assume you use cdrecord-proDVD or something for writing DVD's.
According to Joerg Schilling cdrecord doesn't work 100% with all kernels
newer than 2.6.8 including your "rosetta" 2.6.11 kernel (which you used
for reading?) because for some reason.

I use reiser4 which seems to be available only for 2.6.9+ and have to
reboot to 2.6.8 to write DVD's. Even re-enabling ide-scsi didn't help.
With 2.6.12.3 cdrecord writes DVD's only with single speed here, if at all.

There *may* be an issue there, I haven't had a chance to run it down, so 
I didn't report it. I was burning a set of WBL AS4.0 CDs (not DVD), with 
2.6.12ck4. I was doing the read check of the md5sum after burn, and got 
an i/o error. I repeated this several times, and now have three CDs I 
can't read.

I tried one in another machine and it read fine (2.4.19verypatched). I 
tried it on my laptop, and two machines at home. All read it. I booted 
2.6.7rc1mm1nd (patched 2.6.7 I have been using) and the same CD now 
reads in both the fast USB CD-RW and the built in CD reader. Same Cd, 
same machine. Now up on 2.6.13rc5git1 and can't read it.

It behaves as if the read fails depending on the data read, hard as that 
is to understand with DMA devices and no bounce buffers.

I wouldn't mention this until I had more info, but it seems possibly 
related.
