Did you compile eata into the kernel or as a module? > and the machine locks up after the line: > > clock source tsc unstable http://www.google.com/search?hl=en&sa=X&oi=spell&resnum=1&ct=result&cd=1&q=%22clocksource+tsc+unstable%22&spell=1 http://kerneltrap.org/node/8306 http://lkml.indiana.edu/hypermail/linux/kernel/0707.1/0621.html > Any suggestions? No good ones ... You could put the SCSI controller into another slot and see what happens then --- I've had some SCSI controllers that won't work in one slot but in another, and I've seen network cards working just fine in one board but not in another. You could try older kernels. http://grox.net/doc/linux/howto-OLD-VERSIONS/Module-HOWTO-html/Module-HOWTO-6.html http://ubuntuforums.org/showthread.php?t=472253 https://bugs.launchpad.net/ubuntu/+bug/120426 http://www.google.com/search?hl=en&q=modprobe+eata&btnG=Search find /usr/src/linux/Documentation/scsi -type f | xargs grep -i eata less /usr/src/linux/drivers/scsi/eata.c Try different boot options (/usr/src/linux/drivers/scsi/eata.c): * boot option old module param * ----------- ------------------ * addr,... io_port=addr,... * lc:[y|n] linked_comm=[1|0] * mq:xx max_queue_depth=xx * tm:[0|1|2] tag_mode=[0|1|2] * et:[y|n] ext_tran=[1|0] * rs:[y|n] rev_scan=[1|0] * ip:[y|n] isa_probe=[1|0] * ep:[y|n] eisa_probe=[1|0] * pp:[y|n] pci_probe=[1|0] Read the comments in eata.c, starting at line 323.
