When I burn a CD-R or CD-RW using cdrecord (app-cdr/cdrtools-2.0.1_alpha25, sys-kernel/gentoo-sources-2.4.22-r7) my system clock loses between 2-3 minutes of time. I keep it synchronized with ntpdate, and in this example, it loses 137 seconds. Cdrecord also says the burn took ~290 seconds, and it actually took 427 seconds (by stopwatch). The clock does not lose time during fixating the disc. This worked previously until two nights ago when I changed from 2.4.20-gentoo-r6 to 2.4.22-gentoo-r7. I use sys-kernel/genkernel-3.0.1 to build the kernel and I can attach a copy of the kernel config if needed. root@roam ~ # cdrecord -v /home/error/install-x86-universal-2004.0.iso Cdrecord-Clone 2.01a25-dvd (i686-pc-linux-gnu) Copyright (C) 1995-2004 J

Insert CD-R or CD-RW in drive. 2. Run cdrecord. 3. Reset clock because it's completely wrong now. Actual Results: The system clock (kernel) loses time. In this case it lost 137 seconds though it has occasionally lost more than 200 seconds. Have tested with approximately 17 CDs now. Expected Results: The system clock should not lose any time during burning a CD. This is an IBM ThinkPad R40 2681CU1 with 640MB RAM, 20GB disk, original combo drive used to burn the discs.

try a newer kernel
Installed kernel gentoo-dev-sources-2.6.3-r2 and the problem does NOT occur with this kernel.
Since the newer kernel fixed it, I'm marking this bug closed.
Closed. Issue fixed by updating the kernel.
