[parisc-linux] Status of 2.6.22-rc3 ?

[Helge Deller]

Hi everyone,

I just wanted to ask if someone of you managed to boot a parisc 2.6.22-rc3 kernel yet ?
I'm using Linus' current tree and merged into this one Kyles' latest patches and built the kernel.

I was able to build a kernel after I patched lasi_82596.c (see my patch I sent out just before).
I see quite some warnings though:

I just disabled then the freeing of inital-memory (just in case!), and as such booting to init process went OK.
But then init started udev and it just crashes reproduceably:
->

Anyone sees this as well ?
Is anyone testing head development kernels (e.g. 2.6.22-rc3) at all ?

Best regards,
Helge


PS: I'm not really happy with our current development model. IMHO it's too complicated to get to a building tree and thus too few people (anyone?) test the latest kernels...
