patch to filter module list to list modules once
Cai, Please give this patch a try and confirm that it solves the problem for you. Thanks!
It seems that the patch haven't solved the problem.
First, code in the patch has a little bug:
if [ $? -ne 0 ]
MODULES="$MODULES /lib/modules/$kernel/$fmPath"
fi
Where the line of if condition missed "then", which would cause error.
Then after it was added, it still have the problem:
1. Check the script is patched.
[root@dell-pe1800-01 ~]# cat /sbin/mkdumprd | nl | less
...
277 # only need to add each module once
278 echo $MODULES | grep -q "/lib/modules/$kernel/$fmpath"
279 if [ $? -ne 0 ]; then
280 MODULES="$MODULES /lib/modules/$kernel/$fmPath"
281 fi
...
2. Then cause kernel panic:
[root@dell-pe1800-01 ~]# echo "c" > /proc/sysrq-trigger
...

updated patch
could you try this version please? I might need to quote the MODULES variable to avoid inadvertent behavior in the echo
The new patch still doesn't help. 1. Check mkdumprd is patched [root@dell-pe1800-01 ~]# cat /sbin/mkdumprd | nl | less ... 277 # only need to add each module once 278 echo "$MODULES" | grep -q "/lib/modules/$kernel/$fmpath" 279 if [ $? -ne 0 ]; then 280 MODULES="$MODULES /lib/modules/$kernel/$fmPath" 281 fi ... 2. Then cause kernel panic [root@dell-pe1800-01 ~]# echo "c" > /proc/sysrq-trigger ...

updated patch
Hope you don't mind, poked about on the system you have reserved. This patch fixed the issue for me. Please confirm and I'll commit this ASAP. Thanks!
I tried the latest patch, and did not see the problem again. Red Hat Enterprise Linux Beta 2 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you. |
