When trying to mount an ISO9660 CD on my USB CDRW unit, I get lots of "sr: unaligned transfer" messages from the kernel and the mount command fails. This message was added in kernel 2.5.1 and the sr_scatter_pad() function was removed at the same time. The comment above the message hints that unaligned transfers are (or were) a normal thing. I added a printk to get more information: sr: unaligned transfer sr: sector 64, s_size 2048, bufflen 1024 sr: unaligned transfer sr: sector 68, s_size 2048, bufflen 1024 sr: unaligned transfer sr: sector 72, s_size 2048, bufflen 1024 ... sr: unaligned transfer sr: sector 396, s_size 2048, bufflen 1024 Unable to identify CD-ROM format. So, what changes are needed to make CD support work? -- Peter ?sterlund petero2@telia.com Sk?ndalsv?gen 35 http://w1.894.telia.com/~u89404340 S-128 66 Sk?ndal +46 8 942647 Sweden - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
