Subject: "sr: unaligned transfer" in 2.5.2-pre1
Date: 23 Dec 2001 18:44:43 +0100 [thread overview]
Message-ID: <m2vgexzv90.fsf@ppro.localdomain> (raw)
Hi!
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?
