From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT) Description of problem: When using a CD-ROM 52x LG CRD8522 B on a ServerWorks chipset (e.g. Grand Champion LE ServerSet, ServerSet III HE-SL, ServerSet III LE) with RedHat 7.3 (default i686 kernel, versions 2.4.18-3 / 2.4.18-5) the command 'mount /dev/cdrom' leads to the following message: ide-floppy driver 0.99.newide hda: ATAPI 52x CD-ROM drive, 128 kB Cache, DMA Serverworks OSB4 in impossible state. Disable UDMA or if you are using Seagate then try switching disk types on this controller. Please report this event to osb4-bug@ide.cabal.tm OSB4: continuing might cause disk corruption Afterwards the server hangs, the keyboard is dead. The error occurs independant of Bios settings for the ATA port, even without DMA. It does not occur using RedHat 7.2 or SuSE 8.0. Other CD-ROMs do work properly. This error has been reported to LG as well. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. problem occured on any installation with default kernel, independant of harddisk configuration or packages installed 2. 3. Additional info:
Does this still happen if you disable dma on the cdrom with hdparm -d 0 /dev/hdX (where X is the letter of the ide interface)
When DMA is disabled using hdparm the CD can be mounted. Nevertheless it should work with DMA as it does with other CD-ROMs and with RedHat 7.2, doesn't it.
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
