When I boot the liveCD (universal) the system hangs if I have my A100u2w controller installed. I have an Adaptec RAID 3210S that I boot from. Checking google and the forums shows there appear to be issues with upstream code. However, I would have thought 2005.0 would not have the problem so I'm reporting it.
One of the posts made mention of booting the non-smp kernel but I can't find one on the livecd.
There is no non-SMP kernel anymore. You probably found a fairly old post.
You can try "gentoo nosmp noapic acpi=off" and see if it helps any. You can also try noload=a100u2w if it appears the be the driver locking the system.
I'll try that. Good idea on the noload.
What happens when I build the system and then create a new kernel for the sysetm - (genoo-sources 2.6.11-rx)? Will it have the same error or is it fixed or patched?
It depends entirely on whether it was fixed since gentoo-sources-2.6.11-r3, which is what we used on the InstallCD. I don't follow the kernel changes that closely, but I would suspect that unless it has been patched upstream since the release of 220.127.116.11, then it won't be fixed in our tree, either.
Nope. I tried
gentoo no-smp noapic acpi=off noload=a100u2w
and it still hangs. I guess I'll have to physically remove the board.
Why was the nosmp kernel removed. It seems to me that if would be valuable in cases like this where people's system have trouble with smp. It wasn't a casualty of the "make is smaller" drive was it?
Hopefully the next CD will have a fixed kernel - actually hopefully the current version of the kernel is fixed!
It is nosmp, not no-smp.
The kernel was axed because it isn't as useful as many people seem to think. For one, we no longer offer a 2.4 kernel on the CD. Second, it is possible to make a kernel behave like a uniprocessor kernel with nosmp.
Where exactly are you seeing a freeze? Is there any errors shown?
I had nosmp because I remember seeing only one processor detected and not both.
Where it quits depends. Sometimes the system boots, gets to hardware detection,finds the CPU type and then shortly after that before it starts gpm locks solid. the spinning cursor freezes, ctl-alt-del will not work, I can't switch to another console either. Other times it goes all the way to giving me the livecd prompt and then dumps some SCSI info about the drives, then gives the SCP Reset error and freezes as above.
Ouch... I'm betting that it is because of hotplug/coldplug. What if you try "gentoo nohotplug noload=a100u2w"?
That worked. However a100u2w showed up in lsmod and I had to unload it, then reload dpt_i2o to get the RAID (/dev/sda) to be accessible.
Hrrrmn... it shouldn't be showing up in lsmod at all if you have nohotplug in
there, too... strange
Can you try out the 2005.1-r1 CD that was just released and verify if this
problem is still present? We updated the kenrel to 2.6.12-r10 and it may
resolve this issue.
Sure. I'll have to put the card back in <G> so it may be some time before I get
Not a problem... I just don't have any way of testing this myself, so whenever
you get a chance it would be much appreciated.

Well, we need someone to test this.
