SDB:Triton chipset and busmaster DMA
Symptom:
The EIDE bus system or the ATAPI CD-ROM drive do not work as expected. There might be an error message of the hard drive driver such as:
Ide0 reset timed-out status=0x0d
hdb: irq timeout : status=0xff {busy}
end_request : I/O error, dev 03:44, sector 753688
hdb: status timeout : status=0xff {busy}
hdb: drive not ready for command
or there are errors while accessing the file system (the numbers may vary!):
EXT2-fs warning (device 03:44): ext23_free_inode: bit already cleared for inode 57121,0
EXT2-fs warning (device 03:44) : ext2_unlink: Deleting non existens file (57121),0
EXT2-fs error (device 03:42): bad entry in directory # 3982: rec_len is smaller than minimal - offset=0, inode=2609645352, rec_len=0, name_len=12
attempt to acces beyond end of device 03:42: rw=0, want=651750914, limit=102816
or Yast and/or rpm announce "weird" problems such as: packages have gone lost or certain packages cannot be found.
Cause:
We assume the EIDE system is rather sensible vs. the Triton chipset with busmaster DMA. This occurs mainly if one or two hard drives are attached to the primary controller and the CD ROM is connected to the secondary controller be it master or slave.
Solution:
- Try to keep the cables short in length.
- If there is only on hard drive connected to the primary controller, please attach the CD-ROM drive as slave to the primary controller.
- Disable "busmaster DNA" in your BIOS.
