2.6.23-mm1 s390 driver problem

2.6.23-mm1 s390 driver problem

[Serge E. Hallyn]

Sigh, well this turned out less informative than I'd liked.
After bisecting 2.6.23 to 2.6.23-mm1, I found that
git-s390.patch is the one breaking my s390 boot :(
(Frown bc it's a conglomeration of patches0

Symptom is:
	"Cannot open root device "dasdd2" or unknown-block(94,14)"
even though dasdd2 appeared to be found earlier in the boot.  I also
get

Please append a correct "root=" boot option; here are the available partitions:
...
5e0c 7211520 dasdd driver: dasd-eckd
...
5e0e 6949296 dasdd2

Will keep looking at it, but maybe the fix is obvious to someone
in this cc: list?

thanks,

Can you post the full console output from IPL to the unsuccessful end?

Thanks

Yeah, sorry, appended below.

I had thought that the line
	sysctl table check failed: /sunrpc/transports .7249.14 Missing strategy
meant that the fix referenced in http://lkml.org/lkml/2007/10/11/48
would fix it, but it appeared to have no effect.

This is the vmlinux.lds.S problem. The cleanup patch from Sam Ravnborg
moved the __initramfs_start and __initramfs_end symbols into
the .init.ramfs section. This is in itself not a problem, but it
surfaced a bug: there is no *(.init.initramfs), that needs to be
*(init.ramfs). I corrected this in the upstream patch but 2.6.23-mm1 has
the older one that still causes the "Cannot open root device". For
2.6.23-mm1 use the patch below.

I have a feeling that we fixed this.  But there's no BUG at 2.6.23-mm1's
