2.4.x Problem with cd writing

[Michael Buesch]

Hi.

I've problems with CD-writing since about a half year on various
2.4 kernels (2.4.18 (maybe, I don't remember exactly), 2.4.19, 2.4.2x)

While my writer writes TOC or fixes CD (doesn't write real data-stream),
the whole ide-disk interface of the system is frozen. Kernel ist still
working and all programs run correctly, until they need harddisk
access. No harddisk or CD-ROM access is possible.
After the writer finishes TOC or fixating, the ide-disk interface
defrosts.
