Hi,

just got kernel bug on SLES9 SP3 Oracle 10.1.0.5.

Advice from list 2 months ago was to go back to SP2 (how?)

or switch off async io.

Both is no solution for us.

Is there a new kernel to fix this bug from SuSE?

Investigation via yast/update does not work because firewall is doing
its job too good,

thanks,
kind regards,

Toni
