ASC/ASCQ 0x11/0x06 would appear to mean "CIRC Unrecovered Error".

These values are listed in /usr/src/sys/scsi_base.c, line 1207 and

following. The error text is left out of install kernels to save

space.
Some random Googling gave me
"A CIRC unrecovered data error is defined as a block for which the

CIRC based error correction algorithm was unsuccessful on all read

attempts up to the read retry count. Layered error correction was

not used."

Obvously our read retry count is 3 in this case. I don' know if

the other OS's you tried have larger values and eventually

succeeded, or if they just didn't happen to hit the same block. But

it looks like an inability to read a particular block from that CD

on that system.
