[Bug 92383] Re: WRITE at LBA=288830h failed with SK=7h/ASC=00h/ACQ=00h]: Input/output error

[ilf]

I was able to burn the same command on the exact same hardware and software setup after a reboot.
This is the second time I hit this bug in about five burn times. I cannot make a pattern yet.

When it happens, the drive in question is locked by the kernel and still spinning when it happens.
Only a cold reboot fixes this, "sudo reboot now" didn't help.

This is highly annoying, wasting an empty DVD and having to reboot!

hdparm also fails:
% sudo hdparm -d 0 /dev/sr0
/dev/sr0:
 setting using_dma to 0 (off)
 HDIO_SET_DMA failed: Inappropriate ioctl for device
 HDIO_GET_DMA failed: Inappropriate ioctl for device

% sudo hdparm /dev/sr0     
/dev/sr0:
 multcount     =  0 (off)
 IO_support    =  0 (default) 
 readonly      =  0 (off)
 readahead     = 256 (on)
 HDIO_GETGEO failed: Inappropriate ioctl for device
