I've got several consistent errors that are constantly thrown
into /var/log/messages that I'd like to resolve, listed below.
I'm running a 1.6L kernel (w/ MP), and 1.6-RELEASE userland.

1. This error happens while dialed up to the internet:

Feb 15 17:00:07 kaptah /netbsd: com0: 2 silo overflows, 0 ibuf floods

2. This one happens whenever playing a cd (from cdplay or xmcd):

Feb 15 16:54:14 kaptah /netbsd: cd0(pciide0:1:1):  Check Condition on CDB: 0x28 
00 00 00 00 00 00 00 01 00
Feb 15 16:54:14 kaptah /netbsd:     SENSE KEY:  Illegal Request
Feb 15 16:54:14 kaptah /netbsd:      ASC/ASCQ:  Illegal Mode For This Track
Feb 15 16:54:14 kaptah /netbsd: 
Feb 15 16:54:14 kaptah /netbsd: cd0: dos partition I/O error

3. This is from Dmesg relating to my Zip drive:

sd0 at scsibus0 target 5 lun 0: <IOMEGA, ZIP 250, H.41> disk removable
sd0: could not mode sense (4/5); using fictitious geometry
sd0: 98304 KB, 96 cyl, 64 head, 32 sec, 512 bytes/sect x 196608 sectors
sd0: async, 8-bit transfers
sd0: could not mode sense (4/5); using fictitious geometry
sd0: no disk label
sd0: could not mode sense (4/5); using fictitious geometry
sd0: no disk label

Whenever I mount a zip disk I get the last two lines.

4. This error comes up in my daily report (or from iostat -x):

iostat: sysctl hw.diskstats failed: Invalid argument
