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%. dmesg shows warning: many lost ticks. Your time source seems to be instable or some driver is hogging interupts rip _spin_unlock_irqrestore+0xb/0xd What I changed since last week, is I removed IDE-based DVD drive, and unplugged and replugged the data drives (not the system drive). Any suggestions? I tried adding "clock=pmtmr" to boot options but I still got the message about many lost ticks, time source instable. rip __do_softirq+0x4a/0xd2 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. Any suggestions? Aleksey
