Hi,
After replacing my 2.4.22 with a 2.6.1 kernel I tried ATAPI cd burning.
This totally fails. Most of the CD's are corrupt and my system totally
locks up when erasing an cdrw (reset button was the option I needed to
reboot my system) . k3b reports cd is completely burned but fails are
not identical or totally unreadable. I tried it both with an tainted
(nvidia) and an untainted (nv) kernel: same results. With ide-scsi
burning in 2.4.x I had no problems.

Did you use DMA in 2.4 as well? Does 2.6 work if you turn it off? It's
most likely an issue with your via adapter.

Do you really have an SMP box, or are you just using an SMP kernel? If
you have SMP, it would be interesting to enable the nmi watchdog (if it
works on your system).
Are you using preempt?

I used DMA in 2.4.
I tried without dma on but it still totally locks my system while
erasing an rw.

Could you try disabling preempt?

Its just an smp kernel. I only have one cpu.
Preempt is enabled in kernel

That worked.
preempt= off
dma was on
I don't have an RW, but when my cdrom fixates, it stalls everything
while it's fixating. I have an nForce chipset. (2.6.x)

Does "everything" mean everything on that ide channel? If so, then
that's a hardware limitation.

My IBM A31p (Intel 845 chipset) had a similar problem with the CD
burner. Using the '-immed' flag resolved the issue for me.
