2.4.10ac10, cdrecord 1.9-6, Mitsumi CR-4804TE: lock up burning too large image

[Ville Herva]

When (accidentally) trying to burn ~670MB onto a 74" cdr disk, I experienced
a complete lock up.
                                                                                
It went to 99% (as one would expect), and then drive began giving weird
sounds - as if it was moving the head from start to end over and over. After
a short while, the whole system locked up, no mouse, keyboard, caps lock,
ctrl-alt-del, alt-sysrq-{s,u,b}.
                                                                                
It used to give a nice error when disk size was exceeded with 2.2.18pre19
and a tad older cdrecord (1.9-something (1.10-4 failed on 2.2 BTW, giving
error on mmapping /dev/null)).
                                                                                
I assume this is a kernel thing...
                                                                                
BTW: Also the cd audio ripping speed has dropped from ~8x to ~1x with both
my cdrw and cd drive. The drop took place before upgrading from 2.2 to 2.4. 
I am and was using scsi-emulation for both drives. I tried going back to
older cdparanoia, but it didn't help. Before I try to binary search what has
changed, does anybody have any ideas on what to try?
