During a custom graphical install of Winston Beta-2, the dialog "Transferring install image to hard drive" was displayed. The progress bar was between the words "to" and "hard" when the machine locked up -- could not move the mouse, get to the VT's, or kill X with Ctrl+Alt+Back. A second install using the same options worked fine... buggy hardware driver perhaps? [Intel Seattle 2 (100MHz) mobo, PII-450, 128MB RAM, Diamond Viper V550, three ultra/wide SCSI disks (4.5, 4.5, 9GB) on Adaptec 2940UW controller, one narrow SCSI CD-ROM, one IDE CD-RW drive, 3Com Etherlink 10/100 PCI (3C905C-TX-M). Verified with lsmod that the 3c59x driver is being used for the network hardware, NOT the buggy 3c90x one.]
Most likely a hardware issue - please reopen if this becomes reproducible.
