I upgraded over the net to kubuntu 8.04 from 7.10 and the update basically destroyed my desktop.
If I had been a linux novice I would not have been able to recover from it, but through some trials I managed to get it up and running.
Let me detail my hw environment first:
3.4GHz P4
1GB RAM
motherboard has an nvidia nforce4-sli intel edition chipset
DPT Ultra160 SCSI RAID controller driving 4 18GB 10k drives setup in a RAID5.
That array hosts 3 partitions, / , swap, and /home
1 200GB sata drive broken up into several random storage partitions
1 120GB pata drive which stays unmounted for backups.
nvidia geforce 6600GT pci-express card
I was running the rt kernel in 7.10 so when I did the upgrade the new rt kernel was installed as the default, as expected.
the 1st issue was the update somehow changed the UUID of my root partition, so when it tried to boot it couldn't mount it.
I eventually had to boot to knoppix and figure out the new UUID and manually change it in menu.lst
With that fixed the machine would start to come up but would hang, completely, at various stages. Through more tribulation I finally managed to get the machine up to a console so I could see the kernel spitting out errors from the sata drive. I'm sorry I don't have a screenshot of the errors. When the errors start appearing, the machine is otherwise unresponsive.
I rebooted to the generic kernel and everything runs perfectly fine except I lose my real time capabilities.
I tried to revert to the older kernel, but found to no surprise that the nvidia driver balks at it.. I'm just not interested enough to tackle regressing that just for this issue.
Any ideas on what's going on with the sata_nv module in the rt kernel?
