Re: 2.5.27: Software Suspend failure / JFS errors

[axel@hh59.org]

Hi!

This oops occurred during build of gcc..
Kernel 2.4.19-rc2-ac2.
About the same happens with 2.5.27. I will post an oops of jfsCommit of
2.5.27 as soon as I get one.

ksymoops 2.4.5 on i686 2.4.19-rc2-ac2.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.19-rc2-ac2/ (default)
     -m /boot/System.map-2.4.19-rc2-ac2 (specified)
