Slow DVD-R burning with growisofs under ide-cd
When burning a DVD-R with growisofs, the reported write speed is 4.00x,
but the measured speed is only 0.40x. DMA is on and -20 nicing
growisofs and mkisofs has no effect. Using ide-scsi, I can easily get
4.00x measured speed. However, until ide-scsi stops causing kernel
panics, I'd like to avoid it. My setup is as follows:
Linux Kernel - 2.4.21 + bootsplash patch + updated lm-sensors, bttv,
and v4l2 + loopjari crypto
Processor - Athlon XP 1.26Ghz
RAM - 1GB
DVD+-RW Drive - Vendor: PIONEER Model: DVD-RW DVR-106D Rev: 1.07
DVD-R Media - Some Generic brand labeled "HQ 1X-4X"
For the ide-scsi, the last thing in the log is always of the form:
[kernel] scsi : aborting command due to timeout : pid 555338, scsi0,
channel 0, id 0, lun 0 0x35 00 00 00 00 00 00 00 00 00
I can use sysrq to sync, remount, and boot successfully after the kernel
panic.
