Description Petr Beňas 2011-08-15 13:16:09 UTC
Description of problem:
Discovered IDE cdrom errors in dmesg on kernel rpm install. 
Can be reproduced with fdisk or simply with cat.

Version-Release number of selected component (if applicable):
[root@intel-s3e3144-03 ~]# uname -r
2.6.18-277.el5

How reproducible:
100% on intel-s3e3144-03.rhts.eng.nay.redhat.com. Have not tried on different machines with IDE cdrom.

Steps to Reproduce:
1. cat /dev/hdc
  
Actual results:
[root@intel-s3e3144-03 ~]# cat /dev/hdc 
ATAPI device hdc:
  Error: Illegal request -- (Sense key=0x05)
  Parameter not supported -- (asc=0x26, ascq=0x01)
  The failed "Start/Stop Unit" packet command was: 
  "1b 00 00 00 03 00 00 00 00 00 00 00 00 00 00 00 "
cat: /dev/hdc: No medium found


Expected results:
[root@intel-s3e3144-03 ~]# cat /dev/hdc 
cat: /dev/hdc: No medium found

Petr, is there actually a physical CDROM in the system?  Or is it virtual?

P.

Comment 2 Petr Beňas 2011-08-17 13:31:49 UTC
It should be a physical device.

[root@intel-s3e3144-03 ~]# dmesg | grep hdc
    ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:DMA, hdd:pio
hdc: SR244W, ATAPI CD/DVD-ROM drive
hdc: ATAPI 24X CD-ROM drive, 128kB Cache, UDMA(33)
ATAPI device hdc:
