Comment 3 for bug 321219

I'm suffering from the same bug unter Ubuntu 9.10. The problem can be solved by adding a sleep timer of 20-60s (depends how fast the system is booted) the file "/usr/lib/pm-utils/power.d/95hdparm-apm" before the "hdparm"-command.

"hdparm" is executed twice during the boot, and both commands are called when the boot process do the most I/O-work on the harddisk.

Adding the sleep timer prevents this and "hdparm" will be executed after the heavy I/O-throughput, for example when the login manager appears and is waiting for the login.

For my notebook a 20s timer works perfectly, but
