Subject: can't build IDE as modules in BK 2.5.69

With the 2.5 bk linux as of 2003.05.13, and config options below,
modutils seems to go into a seemingly infinite loop when trying to
buld modules.dep on the resulting module set (and creates an extremely
large modules.dep file -- 95M before the filesystem filled up)

Any ideas?

I'm using gcc 3.2.3 and ld 2.13.90.0.18



CONFIG_IDE=m
CONFIG_BLK_DEV_IDE=m
CONFIG_BLK_DEV_IDEDISK=m
CONFIG_BLK_DEV_IDESCSI=m
CONFIG_BLK_DEV_FLOPPY=m
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_BLK_DEV_ADMA=y
CONFIG_BLK_DEV_PIIX=m
CONFIG_IDEDMA_AUTO=y


depmod -a output:

Grrr... I thought that was fixed. What version of depmod you using
(depmod -V).

Real problem is actual dependency loop in IDE modules, but depmod
should just report that and ignore the modules involved.

Thanks for the report,

OK, reproduced here. I've simplified the depmod loop detection logic:
I was trying to be too clever.

I've just released 0.9.12, which won't help your IDE problem, but will
terminate 8)

http://www.kernel.org/pub/linux/people/rusty/modules/module-init-tools-testsuite-0.9.12.tar.gz

Thanks for the report!
Rusty.
