Description Andre ten Bohmer 2008-01-10 15:58:20 UTC

External firewire disk is sometimes not recognized/connected at reboot since
kernel update (from 2.6.9-55.0.9.ELsmp-prep to 2.6.9-67.0.1.ELsmp-prep).
ieee-1394 support needs to be added to stock kernel, so custom kernel build from
RH source.
Kernel.org 2.6.23.13 kernel runs perfect (kernel.org 2.6.15.1 and so on also had
no problems).

Comment 1 Stefan Richter 2008-01-12 21:07:39 UTC

The IEEE 1394 drivers in Linux 2.6.9 are full of bugs.  Those ancient drivers
cannot be used to do anything serious with IEEE 1394.  It also would be a waste
of time to try to debug them and/or backport the drivers from newer kernels back
to Linux 2.6.9.

Comment 2 Andre ten Bohmer 2008-01-17 13:16:49 UTC

Oke, clear, on RHEL4 boxes using kernel.org kernel instead, thanks
