Hi. I installed FC5 last week. The system disk is a SATA drive. It
showed up as "sda" last week. Now it is "hda". Why did this change?
The other drives, also connected through the on-board SATA ports,
showed up as "sdb" and "sdc" before, and now are "hdb" and "hdc".
More importantly, the performance is broken - CPU %user is 0, system
is like 10, and waiting for I/O is 90%. idle is 0%.
warning: many lost ticks.
Your time source seems to be instable or some driver is hogging interupts
What I changed since last week, is I removed IDE-based DVD drive, and
unplugged and replugged the data drives (not the system drive).
I tried adding "clock=pmtmr" to boot options but I still got the
message about many lost ticks, time source instable.
I am building the latest kernel now, to try with it.
I am really mystified about the switch from "sd" to "hd" in the
drive naming. All the drives on the system are SATA.
