The command growisofs -r -l -J -R -f -graft-points ${=FILES} -Z /dev/hdc always gives: :-[ PERFORM OPC failed with SK=3h/ASC=73h/ACQ=03h]: Input/output error Nothing relevant in dmesg. The drive is Optoride DVD?RW DD0401, the medium is Verbatim DVD-R 8x, and the chipset is i815; Celeron Tualatin 1.4GHZ; Abit ST6R. I tried the growisofs command probably a dozen times, rebooted and powered off in the middle?. I tried a couple of other discs from the same ("known good") batch. cdrecord also fails. I tried to set -speed=1, 2, 4, but growisofs claims setting speed to anything but 8x does not succeed. The drive is able to read CD and DVD media just fine with 2.6.13.1. I booted back to 2.6.12-rc4 and the recording succeeded at the first try. I used the exact same disc that had failed with 2.6.13.1. The .config from 2.6.12-rc4 and 2.6.13.1 is nearly identical, but with 2.6.13.1 I use HZ=250 (that being the default nowadays) and 2.6.13.1 has CONFIG_PREEMPT_VOLUNTARY=y instead of 2.6.12-rc4's CONFIG_PREEMPT=y and CONFIG_PREEMPT_BKL=y ?. Any ideas? -- v -- v@iki.fi ?) In past, the DVD-R drive has sometimes gotten so confused it needs a power off before it co-operates. However, in those cases it has stopped responsing altogether, which it didn't do this time. ?) The desktop does seem more responsive with 2.6.13.1- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
