Red Hat Bugzilla – Bug 73891
Third PDC20269 controller in system dosen't work
Last modified: 2008-08-01 12:22:52 EDT
Description of Problem:
When I install three Promise PDC20269 chipset-based ATA-133 controllers (Maxtor
Ultra 133 TX2) in my system, the drives on the third controller are not
accessible. The ide subsystem recognizes the presence of the drives, but
reading and writing to them is not possible and throws errors on the screen.
I've played around with hdparam trying to get the drives to work without
success. I have had success with a mandrake kernel that looks like it has a
later version of the ide driver code. (More on that below.)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install three Maxtor Ultra 133 TX2 controllers.
2. Attach a drive to each controller.
3. Boot into kernel-2.4.18-5
4. Read the first block from the last drive.
[root@remotebackup root]# dd if=/dev/hdo of=/dev/null count=1
dd: reading `/dev/hdo': Input/output error
0+0 records in
0+0 records out
The following is logged to the console:
end_request: I/O error, dev 59:00 (hdo), sector 0
end_request: I/O error, dev 59:00 (hdo), sector 2
end_request: I/O error, dev 59:00 (hdo), sector 4
end_request: I/O error, dev 59:00 (hdo), sector 6
[root@remotebackup root]# dd if=/dev/hdk of=/dev/null count=1
1+0 records in
1+0 records out
I've been using the Mandrake version kernel-18.104.22.168.1mdk-1-3mdk which allows
all three controllers to work without problem. No hdparam settings are
required. So, I think this problem has been fixed in later ide driver code.
For your convenience, here is the kernel that works:
