[2.6.13] pktcdvd: IO-errors

[Guennadi Liakhovetski <g.liakhovetski@gmx.de>]

Hi all

Just tried pktcdvd on 2.6.13.1. The setup went fine:

20:33:13: pktcdvd: writer pktcdvd0 mapped to hdc
20:33:21: pktcdvd: inserted media is CD-RW
20:33:21: pktcdvd: Fixed packets, 32 blocks, Mode-2 disc
20:33:21: pktcdvd: Max. media speed: 10
20:33:21: pktcdvd: write speed 10x
20:33:21: pktcdvd: 590528kB available on disc
20:33:23: UDF-fs INFO UDF 0.9.8.1 (2004/29/09) Mounting volume 'LinuxUDF', timestamp 2005/09/24 20:18 (1078)

But, as I tried to copy some files to the CD-RW, it first went ok, but 
then produced the following:

20:41:01: ide-cd: cmd 0x2a timed out

...

the "cp" finished earlier, I did a sync, and it also finished. The good 
parts - no Oops, no process stuck in "D", tha bad parts - it didn't 
work:-), the IDE LED stays on and I cannot eject the CD. The CD-R is a 
BenQ 52x32x52 Seamless Link alone on ide1, the disk does indeed say 
4x-10x. The cd-writer works mostly... if I am gentle to it - I usually 
burn at 32x even if the media says 52x... Is it just a hw-failure or a 
driver bug?

Thanks
