6.2-RELEASE panic when blanking CD-RW media

I've encountered a deterministic kernel panic when
blanking one specific CD-RW media using cdrecord.

# cdrecord dev=2,0,0 blank=fast

The kernel panic details follow and dmesg is at the end of this
email. Though I understand there's something wrong with the media,
I think it shouldn't panic the kernel either.

Thanks in advance for looking into this,
