In Reply to: [gentoo-sparc] Keyboard problems in 2.6.7-gentoo (was: ALSA support on sparc) by Jeremy Huddleston
Has anyone actually tried to find which patch breaks the keyboard?  I'd
like to get this keyboard thing fixed in g-d-s, and since I'm not
affected, I can't test it...

Also, what are the specific problems preventing us from going up to
2.6.8 (and even 2.6.9) over 2.6.7?  The main issues that I know of which
are not resolved in 2.6.7-gentoo-r17 are:

* SMP "broken" - for all 2.6.x
* Hypersparc DMA broken (patch on sparclinux) - for all 2.6.x
* hme doesn't work on Hypersparc - 2.6.9

* SMP with high load causes lockup - for all 2.6.x
* high load / disk access causes (rare) lockup on UP and SMP (reported
for a US II on 2.6.0-test10 and 2.6.9) - AFAIK, for all 2.6.x
* stop-a doesn't work over serial console (patch on sparclinux, but I
don't use serial console, so I haven't tested it) - for all 2.6.x
* keyboard sometimes doesn't work - 2.6.7-gentoo-rx

No issues that I see were added with 2.6.8, and additionally, I've been
running g-d-s-2.6.8-r10 (with the sparc patch set forward ported from
2.6.7-r17) without a hickup for the past day, and it's been constantly
running 'dbench 32' for the past 90 minutes... I have a UP UltraSparc
IIi... so would someone like to fill me in?  Is it a sparc32 specific
reason that I missed?
