Dell PowerEdge T105 optical drive [message #32088]

Hi!

PowerEdge T105 is a budget server from Dell apparently suitable for inexpensive virtual server setup.

However, there are some issues with its SATA optical drive. Apparently the sata_nv driver and a 4+ GB RAM are a bad match up.

I am trying to use ovzkernel in CentOS 5.2. Version 2.6.24 will make the system hang when the HAL service starts. Version 2.6.18 will boot, but will crash+reboot the system when trying to mount the CD drive (mount /dev/scd0 /mnt).

At some sites I have seen recommended to append "sata_nv.adma=0" to the kernel boot options to work around this issue, but it won't help in this case.

Before I try to build and test a custom 2.6.26, I was wondering if someone has any better advice.

Regards,

Luis

Hello,

1. Are you sure that total amount of RAM is really matter? Could you please, decrease the total amount of RAM for example by using "mem=value" in the kernel command line in appropriate bootloader configuration file.

2. Do you know the kernels where the combination of hardware/drivers you've described above works?

3. Could you please show "lspci" and "lspci -n" from HN.

Thank You!

1. Yes. I tried mem=3G and it worked. Apparently you can even raise it to mem=4096M. There is more information on the issue here:

http://lkml.org/lkml/2008/1/10/163
https://bugzilla.redhat.com/show_bug.cgi?id=351451

It seems that there is a patch but either it is not effective or it didn't make it to 2.6.24.

What puzzles me is that RHEL5 is officially supported by Dell and I haven't been able to find any reference to this issue for that distro, only for CentOS, Ubuntu and Fedora. Either no one installs RHEL on this machine or RH has released a patched kernel and it hasn't made it to CentOS.

2. No, I don't, I guess when I have some spare time I will try some 2.6.25 or 2.6.26 or try to find if a patch has finally been released and try to backport it to 2.6.18 or 2.6.24.

3. Find the output of the commands you requested below. Thanks a lot for your answer.
