Found out that if you add "ide=nodma" to the kernel line, the 2.4.9 kernels work correctly. The "ide=nodma" is a little too harsh, because it kills DMA on IDE disks too. A better workaround is to use hdparm -d0 /dev/hdb. This is an ongoing problem somewhere in bowels of IDE framework. Apparently, the old 2.2 IDE did not hit hw too hard. Last note - I suggest to use ide-scsi and st instead of ide-tape. The latter is a poorly implemented driver, with bugs crawling all over it. *** This bug has been marked as a duplicate of 54517 *** |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98) Description of problem: IDE tape drive inside the RedHat kernels 2.4.9-6 and 2.4.9-21 does not work properly. It does work under RedHat kernel 2.4.7-10. System is Intel Pentium III 1.0GHz in Intel I815EGEW mainboard using primary IDE controller with CD-ROM as master and TAPE as slave drive using 80pin IDE cable. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. boot up 2.4.9 kernel 2. start CPIO or TAR to write data to tape 3. watch it not work. Actual Results: Errors listed in /var/adm/messages. Initially the drive status LED will remain on while the system is timing out. After the timeout the drive will start to rewind then report "end of medium found. insert next tape." Expected Results: Create tape with hard drive contents on it.
