First Ux I try to boot, on install I get this:
WARNING: /lib/modules/2.6.8-1.520.1rU7.ll.rhfc2.ccrma/kernel/drivers/scsi/aacraid/aacraid.ko needs unknown symbol __you_cannot_kmalloc_that_much WARNING: /lib/modules/2.6.8-1.520.1rU7.ll.rhfc2.ccrma/kernel/drivers/message/i2o/i2o_block.ko needs unknown symbol i2o_msg_in_to_virt WARNING: /lib/modules/2.6.8-1.520.1rU7.ll.rhfc2.ccrma/kernel/drivers/message/i2o/i2o_core.ko needs unknown symbol i2o_msg_in_to_virt WARNING: /lib/modules/2.6.8-1.520.1rU7.ll.rhfc2.ccrma/kernel/drivers/message/i2o/i2o_core.ko needs unknown symbol i2o_msg_out_to_virt WARNING: /lib/modules/2.6.8-1.520.1rU7.ll.rhfc2.ccrma/kernel/drivers/message/i2o/i2o_scsi.ko needs unknown symbol i2o_msg_in_to_virt
No luck booting, I get a kernel panic, the last lines printed to the screen are like this (transcribed by hand, there may be errors):
