Bug 2518 – Broken gentoo-sources-2.4.19-r3

• Product: Gentoo Linux
• Status: VERIFIED FIXED

[Description Matt Boehlig 2002-05-07 04:47:54 UTC]

There are a couple problems with the new 2.4.19-gentoo-r3 kernel.  2.4.19-gentoo-r1 works fine for me.

http://lists.gentoo.org/pipermail/gentoo-user/2002-May/022770.html also describes this problem.  I enabled low latency and disabled preemptive and I get an error compiling: 

ksyms.c:454: `preempt_schedule' undeclared here (not in a function)

ksyms.c:454: initializer element is not constant

ksyms.c:454: (near initialization for `__ksymtab_preempt_schedule.value')



If I enable preemptive, then the compile has no problems.  



Once the kernel compiles there is another problem.  On bootup I get a kernel panic.  I think it's with loading kswapd.  It says something about swapper.o, spews out a bunch of registers, and then somthing like kernel panic!! init trying to kill itself.



I am have used the same .config from my working kernel, enabled/disabled apm, acpi, low latency, preemptive (which does not work disabled).  I still get kernel panic on boot.

This patch should, at least in theory, fix the preempt problem. Untested. What
could the kswapd problem be caused by?

CONFIG_PREEMPT fix

Yep, that'll fix it.  I'll roll out a new kernel soon.

[Comment 4 Daniel Robbins (RETIRED) 2002-05-08 00:52:14 UTC]

Fixed in gentoo-sources and crypto-sources r4.  Now on CVS; will be on rsync soon.

Yep, it's fixed.  I'll make my kernel panic a new bug.
