2.4.19-pre7-ac2: Promise Ultra100TX2 broken

2.4.19-pre7-ac2: Promise Ultra100TX2 broken

Post by Dennis Stosber » Sun, 28 Apr 2002 03:00:12



Hello,

In the late 2.4.19-preX-acY the support for the Promise
Ultra100TX2 is broken. This problem was already reported on
lkml and on the German SuSE Linux mailing list. According to
information from that list the problem only affects the
Ultra100TX2, but NOT the Ultra100TX.

The latest -ac kernel I know to work with this controller, is
2.4.19-pre2-ac4. I just tried 2.4.19-pre7-ac2: it
fails. 2.4.19-pre4-ac3 has also been reported to fail:

http://www.ussg.iu.edu/hypermail/linux/kernel/0203.3/1011.html

At boot time 2.4.19-pre7-ac2 prints these error messages. The
drives ARE conntected using an 80-pin cable:

hde: set_drive_speed_status: status=0xff { Busy }
Warning: Primary channel requires an 80-pin cable for operation.
hde reduced to Ultra33 mode.
[..]
end_request: I/O error, dev 21:00 (hde), sector 0
end_request: I/O error, dev 21:00 (hde), sector 2
end_request: I/O error, dev 21:00 (hde), sector 4
end_request: I/O error, dev 21:00 (hde), sector 6
end_request: I/O error, dev 21:00 (hde), sector 0
end_request: I/O error, dev 21:00 (hde), sector 2
end_request: I/O error, dev 21:00 (hde), sector 4
end_request: I/O error, dev 21:00 (hde), sector 6

You can find the configuration of the failing kernel at:

http://stosberg.net/tmp/config-2.4.19-pre7-ac2

Currently I'm using 2.4.19-pre5aa1 without problems.

Regards,
Dennis

Apparently not for everyone. I'm using one such card with
a 20G Western Digital drive on 2.4.19-pre7-ac2 w/o any problems
apart from having to pass 'ide2=ata66' to get the driver to
allow me to use UDMA4/5 (yes, the drive *is* attached using
an 80-wire cable). The U100TX2's BIOS rev. is 2.20.0.11.

My controller uses the same BIOS version.

I would appreciate that. Maybe the problem is caused by some
combinations of the configuration.

2.4.19-pre7-ac2: Promise Ultra100TX2 broken

Post by Dennis Stosber » Sun, 28 Apr 2002 23:30:09



Quote:> Be my guest. :)

Thanks. The problem persists with your .config. I guess I have
to make out the change that breaks my config in the source.

I will report, if I succeed.

Regards,
Dennis

Please read the FAQ at  http://www.tux.org/lkml/

 
 
 

1. Process hangs in 2.4.19, RH7.latest, and 2.4.20-pre7-ac2

I (and other people) have seen process hangs on stock 2.4.19, 2.4.20-pre7-ac2,
and (iirc) the latest RH 7.x kernel.  Any process that does the moral
equivalent of ps hangs.  The machine quickly becomes unusable, and needs to
be crashed.

It's been seen most often under heavy UML load.  I've seen it most often
doing UML development inside UML (stock 2.4.19).  It's been seen on
2.4.20-pre7-ac2 on a UML server.  However, I have had it happen with no
UMLs in sight.

We finally got sysrq information on this.  The hung processes all look like
this:
        Proc;  ps
        >>EIP; e352bef4 <_end+2307b320/386c042c>   <=====
        Trace; c032a955 <rwsem_down_read_failed+195/1c0>
        Trace; c016e3c0 <.text.lock.array+73/123>
        Trace; c016b340 <proc_info_read+50/110>
        Trace; c0148736 <sys_read+96/190>
        Trace; c0147fb3 <sys_open+53/b0>
        Trace; c01092cb <system_call+33/38>

The lock in question is the mmap_sem being acquired in proc_pid_stat.  There
should be a sleeping process which is holding the semaphore, but I haven't
spotted it among the multitudes that were running at the time.

The full ksymoops-ed sysrq-t output is available at
        http://www.stearns.org/slartibartfast/sym_stacks

I'm not including it here because it's too large.

There should be one process which started this by grabbing a mm_sem and
sleeping forever and I would think its stack would be different from all
the others.  There are a few processes whose deepest IP are unique:

Proc;  grep
Trace; c0118120 <do_page_fault+0/438>

Proc;  killall
Trace; c0130b72 <__vma_link+62/c0>
Trace; c032a955 <rwsem_down_read_failed+195/1c0>
Trace; c016e3c0 <.text.lock.array+73/123>
Trace; c016b340 <proc_info_read+50/110>

Proc;  init
Trace; c013f5e3 <__get_free_pages+13/30>

None of these look like to culprits.  init is probably innocent, the grep
was processing the output of a hung ps, so it was too late, and the killall
is itself hung.

I'd appreciate any clues about what's going on here.  If anyone needs more
info than what's in the sysrq output at the URL above, contact me or Bill
Stearns (wstearns at pobox dot com).
