Not after the probe, but when I try to mount a file system:

or when I try to run disklabel:

I'm using 5.99.24/amd64 from March 11, which is the first time I saw
this problem. Since you asked, I've tried to go back to earlier
kernels, but the oldest 5.99.24 I have (from January 20) produces the
same symptoms now, which confuses me, since I'm sure I used the CD
drive successfully at least on Feb 14 (I still have the flacs from
that day) Trying to rip the same CD today (using pkgsrc/audio/abcde)
hangs for a long time, process status according to top is:
 2221 wiz       85    0  5376K  592K xscmd/3    0:00  0.00%  0.00% cd-discid
Then reports
cd-discid: /dev/rcd0d: CDROMREADTOCHDR: Operation not supported by device
abcde error: CD could not be read. Perhaps there's no CD in the drive?
and dmesg now has
cd0(ahcisata1:1:0):  Check Condition on CDB: 0x35 00 00 00 00 00 00 00 00 00
    SENSE KEY:  Not Ready
     ASC/ASCQ:  Incompatible Medium Installed

Can hardware failure look like this?
Do you have another hypothesis?
