Note, this should probably read:
	hung bootup for drivers built into the kernel, that fail their
	module_init() call.

A much smaller minority of cases :)

I have now even better one with pata_via.  A kernel, which for
all practical purposes is 2.6.21-rc5, not only refuses to boot
(and I cannot find some option combination which would allow me to
do so anyway) but simply refuses to read _any_ data from a media.
This included a partitioning information.

Earlier kernel on the same hardware boots without raising any fuss.

Jens, does suspend to RAM also work for you with the latest -git?

If I understand this correctly, a plain 2.6.20 kernel is already broken?

You mean that a quoted report talks about 2.6.20-1.3025.fc7 kernel?
These are vagaries of kernel version numbering in Fedora.
Changelogs are not that clear but it appears that
2.6.19-1.2911.6.4.fc6 will be actually closer to 2.6.20.
That kernel from a bug report is really, for all intents and purposes,
2.6.21-rc5 (if I am not misreading something).

I am afraid that I do not have at this moment an easy to way to check
"plain" 2.6.20 on the hardware in question.  It appears that the
essential difference is that a working kernel is using and old IDE
driver, and sees the drive - in this case - as /dev/hdc, while the
current one tries to go through libata and chockes uncontrollably.
