Upgrading from Edgy to Feisty resulted in a similar situation. It is never able to find the scsi drives.
The machine is an hp x4000 dual-xeon. As a note: this works fine in debian testing/lenny and all previous debian releases (back until stable at least). This was also working fine in edgy eft. I have reverted back to debian/testing since feisty didn't work out (for now). I've attached the output of lspci. I am led to believe that it is a problem with the raid/scsi drivers. The one in this machine is: SCSI storage controller: LSI Logic / Symbios Logic 53c1010 66MHz Ultra3 SCSI Adapter (rev 01) Again, debian-installer in debian/testing handles this configuration just fine. Feisty is very slow while detecting hardware and later asks me to select drivers. Selecting the sym53c8xx driver did not resolve it. Interestingly, I had this same exactly problem back with Edgy as well. I was able to install Edgy by first installing Debian/Etch, changing sources.list and upgrading to Edgy. The worked just fine. I'm a little curious about whether this would work again for Feisty, but I'd rather not hack it. After a few months of using Edgy I followed http://www.howtogeek.com/howto/ubuntu/upgrade-ubuntu-edgy-to-feisty/ . After the upgrade, the system was hosed (likely because it brought along the new kernel). I then tried installing afresh from the minimal feisty iso and ended up with the same results. Thanks for reading this! Let me know if there's any way I can help. ** Attachment added: "output of lspci -vvx" http://launchpadlibrarian.net/8275317/lspci.txt -- [Edgy beta] Kernel freeze with sym53c8xx on AMD64 https://bugs.launchpad.net/bugs/64514 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
