Description of problem:
Installed hangs and times out when loading anaconda, after selecting what
kind of install to use.
Steps to Reproduce:
1. Start installation in "expert text" mode
2. Choose Custom Install (or any install)
Actual Results: The system, in the first virtual window, only showed the
blue background of the RedHat installer.
Expected Results: It should have continued and allowed me to install RH7.1
Error message encountered, after htting "Alt-F4":
<4>SCSI: aborting command due to timeout: pid 0, scsi 0, channel 0, id 0,
lun 0 0x28 00 00 00 00 00 00 00 02 00
<4>scsi0: Aborting CCB#39 to target 0
<4>SCSI host 0 abort (pid 0) timed out - resetting
<4>scsi0: Sending bus device reset CCB#40 to target 0
<4>SCSI host 0 abort (pid 0) timed out - resetting - trying harder
<4>SCSI bus is being reset for host 0 channel 0.
<4>scsi0: Resetting BusLogic BT-950 due to target 0
<4>scsi0: *** BusLogic BT-950 Initialized Successfully ***
Then, it repeats the error message indefinately.
I have a Mylex FlashPoint LT Ultra SCSI, with lated BIOS, running two 9.1
gig Quantum Ultra SCSI hard drives and a Yamaha SCSI CD-RW and a Teac SCSI
CD-ROM. I'm trying to install RH7.1 from a boot disk and an IDE
CD/DVD-ROM. My system is an Athlon 700 Slot A, 256 mb RAM. Motherboard is
an MSI-6167 with latest BIOS. I have a RIVA TNT2 video and 3com 3c905c
network card and a SoundBlaster AWE64 ISA.
I've tried all of the tricks related to the recent aic7xxx, including the
boot disk (I thought the problems were similar) but it didn't work.
RH7 worked fine with my system.
I believe I have this problem as well.
P-III, 440BX chipset, Mylex Flashpoint, thee 9G drives, DAT, CD-ROM.
Attempting a hard-disk install. Boot from floppy, select text install, enter
location of isos,
hang. On console 4, a continuous stream of SCSI bus resets.
Can you try booting with 'linux ide=nodma'? Does that help?
I tried "linux ide=nodma" and it doesn't help. Same situation.
Is there any progress on this issue?
I can also confirm that linux ide=nodma is no help.
Buslogic worked in our testlab.
"noprobe" is the only option I can think of that might make a difference
I finally got to try "noprobe" (the machine lives in Baltimore and I live in
South Carolina) and it didn't help. It asks for a controller, and when BusLogic
is selected, it goes through the same sequence of events.
Here, laborously copied off the screen, is the sequence of messages. This time
I tried the install off of CD (SCSI ID 3).
After whaqt appear to be the usual startup messages, ending with "Unable to
identify CD-ROM format", we see:
SCSI Aborting command due to timeout pid 10, scsi 0, channel 0, id 3, lun 0
0x28 00 00 04 32 7a 00 00 06 00
Aborting CCB #666 due to Target 3

SCSI bus is being reset for host 0 channel 0
SCSI0: Resetting Buslogic BT-950 due to Target 3

Then the last three messages repeat indefinitely.
I installed an Adaptec 2950 and the install went off without a hitch. Now I
will try to use the BusLogic as a second adapter.
This card had the RAID BIOS installed. I have two more machines to install when
I return from traveling. One has a BT-950 without the RAID, and the other has a
I have the same problem.

I get virtually the same set of messages at console F4 as mjs and bfotovic.
Except the CCB code is #1311 and #1312. IDE is disabled in the motherboard BIOS
as this is an all-SCSI box. System continually tries to read Target 2 (CD-ROM),
and upon failure, resets SCSI bus. The OS does recognize the BT-950 itself.
I am attempting an upgrade to an existing Redhat 5.2 system which installed
without incident on the same hardware and has been running flawlessly 24/7 for
over two years (average uptime over 120 days).
Me too. :) -- PII SMP; BusLogic Model BT-958 PCI -- Firmware Version: 5.07B
Upgrading from kernel-smp-2.4.3-12 to kernel-smp-2.4.9-12 (rh7.1) failed, with
similar timeout errors. According to the support web site for the card, the
latest version of firmware is "4.96F/5.06I"
I also encountered similar troubles with a kernel I compiled...
A kb article on the mylex support site suggests that firmware v. 5.07B may have
issues: "Firmware 5.07B has a known problem with the diagnostics, and with
hanging, and the work-around is to reflash the adapter back to firmware 5.06I or
An email to their support apparently got filed in /dev/null. I'm building a new
machine, and after that's running I'll dig up a DOS boot diskette and try a

You definitely want to do this, probably with 5.06J (available from
I installed 7.2 from a CD-ROM on a BT-958 with that BIOS combination to an
ATA-100 disk drive, and it's working fine so far. Haven't had a chance to try
the BT-950 yet.
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
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/
