https://bugzilla.novell.com/show_bug.cgi?id=214909 ------- Comment #23 from seife@novell.com 2006-11-10 01:49 MST ------- no. Booting / detection is pretty fast, but apparently barrier writes on ext3 take a long time, thus "barrier=0" mount option "fixes" it. During installation, after every rpm installed, there is a ~5 seconds stall. I guess that RPM is doing some flush after every package. I'm using only ext3 on this machine. d119:~ # hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 96 MB in 3.05 seconds = 31.47 MB/sec i can only boot with piix when i'm back in the office. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

IDE and libata both export identical barrier capability to upper layer for the same drive. Can you please post the result of 'hdparm -I' of your disk? libata and IDE might use different command for cache flushing under certain circumstances and that could be causing the difference here. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
