Description Kasper Dupont 2003-05-14 23:10:37 UTC
Description of problem:
Enabling DMA and IRQ unmasking on DVD drive causes problems.

Symptoms are
1) DVD not correctly detected
2) Error messages about hda
3) Error messages about hdb
4) System lockups

Version-Release number of selected component (if applicable):
kernel-2.4.20-13.9 fails during boot
kernel-2.4.20-9 works without problems

How reproducible:
Every time

Steps to Reproduce:
1. add "hdparm -u1 -d1 /dev/hdb" to /etc/rc.local
2. Boot kernel-2.4.20-13.9
Actual results:
Slightly different from boot to boot.
No message about DVD drive being detected.
Sometimes 1-3 error messages about hda, but system apears to be working:
  hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
  hda: drive not ready for command
Other times 10 or more error messages about hdb, and system lockup.
Only SysRq+B works.

Expected results:
Like 2.4.20-9
DVD drive being detected prints:
   hdb: ATAPI 40X DVD-ROM drive, 512kB Cache, UDMA(33)                            
And DMA and IRQ unmasking gets enabled without error messages and
works flawless. 

Additional info:
The computer is a "F@MILY net"

Output from "dmesg|grep -i1 'hd\|ide'" on a working kernel:
