2.6.18: unable to handle kernel paging request at virtual address e5e9ec24

2.6.18: unable to handle kernel paging request at virtual address e5e9ec24

[admin]

Hi,

I get repeated times (approximately every 2 days) a similiar exception
with kernel
2.6.18 ?

I never noticed a problem like this using 2.6.17.

Does anyone have any suggestion what could go wrong ?

Thanks in advance
Bye,
David Arendt

Yes, this:

Binary modules loaded. Don't do that.

To elaborate bit on what Martin said here, there aren't many
developers on LKML that are willing to debug a tainted kernel. Please
reproduce without any binary-only modules and post the results to get
help. Thanks.
