[PATCH] Drop the old Adaptec AIC7xxx driver
by Paul Bolle
Ever since v2.4.3 this driver is advertised as not being under active
development. It's main advantage to most users will be the warnings it
generates at build time:
drivers/scsi/aic7xxx_old.c: In function ‘aic7xxx_register’:
drivers/scsi/aic7xxx_old.c:7901:5: warning: case value ‘257’ not in enumerated type ‘ahc_chip’ [-Wswitch]
drivers/scsi/aic7xxx_old.c:7898:5: warning: case value ‘513’ not in enumerated type ‘ahc_chip’ [-Wswitch]
drivers/scsi/aic7xxx_old.c: In function ‘aic7xxx_load_seeprom’:
drivers/scsi/aic7xxx_old.c:8517:5: warning: case value ‘257’ not in enumerated type ‘ahc_chip’ [-Wswitch]
drivers/scsi/aic7xxx_old.c:8510:5: warning: case value ‘513’ not in enumerated type ‘ahc_chip’ [-Wswitch]
Let's drop this old driver.

0) I'm trying to get my kernel builds (which use the Fedora kernel
config) warning free. Upstream declined the brilliant fix to silence
these warnings (see https://lkml.org/lkml/2012/9/21/104 ).
1) Plan B is to simply drop this old driver in the Fedora kernel
altogether. That should silence these warnings too, shouldn't it? But is
dropping this old driver acceptable?
2) This patch is entirely untested.

Debug slowness test results
by Adam Williamson
Hey, folks. I've discussed this with jwb on IRC, but mailing it too to
make sure the results don't get lost. I tested all the recent kernel
builds on my nouveau (9600 GT) desktop and a selection on my Intel
laptop, using gtkperf and x11perf (x11perf at ajax's request) as quick
and dirty benchmarks, and got the following results. gtkperf tracks very
closely with my subjective perception of performance - when the gtkperf
numbers jump, those are the kernels that feel very slow to me. I don't
really perceive the jumps that are unique to x11perf numbers.
It seems pretty clear from these numbers that slub_debug is the biggest
offender for me, according to jwb. I didn't put the results in the chart
for some reason, but on the nouveau machine just like the intel one,
rc5.git1 with slub_debug=- as a kernel parameter gives a fast gtkperf
time - in the 2.4-2.5 range - and 'feels' perfectly fine, that's what
I'm running right now.

F17 Debug Kernels fails to boot (non-debug kernels are able to boot normally)
by Reartes Guillermo
Hi,
I am new to the list, i am experiencing a bizzarre issue with debug
kernels. I used debug kernels in the past without issues.
The issue is that the last two debug kernels i tried do not boot. So i
cannot boot debug kernels.
Kernels that boot normally:
3.7.3-101.fc17.x86_64
3.7.4-104.fc17.x86_64
(and olders)
Kernels that do not boot.
3.7.4-104.fc17.x86_64.debug
3.7.3-101.fc17.x86_64.debug
(older kernels untested)
It is perceived as a increasing slowness in dracut but when one press
ESC one will find that "Watchdog detected hard LOCKUP on cpu 1! and a
call trace, in fact, there are many call traces in which the cpu
number changes. Ultimatelly, one needs to press the reset button.
HW: FX-6100 on 990FX chipset
Thanks in advance.
