Please install the latest errata kernel, (which will likely have the same bug), and attach the output of the dmesg command here. Thanks. Created attachment 303962 [details]
Output of dmesg
The problem still exists and is unchanged after a fresh install and running yum update to apply the latest updates. The output of uname -a is: Linux home 2.6.24.4-64.fc8 #1 SMP Sat Mar 29 09:54:46 EDT 2008 i686 i686 i386 GNU/Linux The disk should be recognized here as ata2.00: ata2: port is slow to respond, please be patient (Status 0x80) ata2: SRST failed (errno=-16) ata2.01: ATAPI: ASUS DRW-1608P3S, 1.24, max UDMA/66 ata2.01: configured for UDMA/66 Is the cabling right on this channel? libata is a lot pickier than old IDE about drives being jumpered correctly and connected to the right connector on a parallel cable. Thanks Chuck. Spot on. The cable end that typically goes in the controller was in the CD drive, with the center connector in the controller, and the short lead to the hard drive. The jumpers were correct. I relocated the hard drive to be near the CD drive, and with the two connectors that are close to each other, connected one in the CD drive and one in the hard drive, with the long lead going to the controller on the motherboard. Other than relocate the hard drive, the only thing I did was change the IDE cable around, and it is now working fine. Once again, thanks Chuck, well spotted. The only last comment I have, is that older versions of Linux handle the reversed connection of the IDE cable, and for the less technically competent user than I, they may find swapping around an IDE cable outside their abilities. Basically for the average home user, they would be unable to resolve this problem, and for some users, unable to install Fedora Core 8. Therefore I encourage that this bug report remain open, until a fix to the kernel/libata is made to make it more tolerant of cabling. Maybe Alan can explain why libata is pickier than old-IDE about correct PATA cabling... I sure can't. Nor me - and I've also seen the reverse case. With a dodgy cable you are into timing and luck when the drives come up and it may just be that because we reset the bus to get a clean start that this happens to cause a timing problem between the drives due to the wrong cable. Given PATA command blocks are never checksummed I think I prefer the failure case to obscure random corruption anyway. I have been running with this configuration since purchase of this computer around two years ago. The computer was configured by the assembler in this configuration prior to my purchase. The only thing I did was to add two drives on the other controller. Having the center connected to the controller on the motherboard, has worked fine excepting that now I have changed it around, I can see that the bios was handling the boot slowly. It is booting much faster now. I don't believe there to be any physical problem with the cable. It is just that it was installed in a non optimal direction. It surprised me that changing the cable around made a difference. Because Windows and versions of Linux prior to the latest releases, handle the alternate arrangement of the IDE cable fine. It is just the latest releases of Linux that have a problem with the non optimal arrangement. After changing the cable around, and seeing this fixed the problem, I changed it back. The problem returned. I then changed it around to having the long end to the controller again, and it works. |
