Subject: Re: 2.6.20-rc6 libata PATA ATAPI CDROM is not working
Hello Tejun,
A small update:
your patch also works against 2.6.20
but seems that open the door to numerous other pb:
1/ pb to burn cd:
# md5sum cd060213.iso
6a1248783a21722816b972aa9bae9d5e cd060213.iso
# ll cd060213.iso
-rwxr-xr-x 1 root root 3213312 Feb 13 2006 cd060213.iso
# dd if=/dev/sr0 bs=1 count=3213312 | md5sum
dd: reading `/dev/sr0': Input/output error
0337e9846d17779945c5c252d4f897f0 -
3129344+0 records in
3129344+0 records out
3129344 bytes (3.1 MB) copied, 36.6963 seconds, 85.3 kB/s
eventhought cdrecord seems to be successfull???
2/ (but that should be much more related to scsi api) sdcXX > sdc15 doesn't works ;-(
