| |
After I upgraded from 2.6.12-rc4 to 2.6.13.1, I can no longer write DVD-R (haven't tried DVD+R nor CD-R).
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 middle¹. 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 ².
Any ideas?

¹) 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. ²) The desktop does seem more responsive with 2.6.13.1-
