Please update with the following information:
1 - Version of LTP that you are using to produce the abort01 test hang
2 - Output from "uname -a".
1. LPT is last cvs version, updated yesterday.
2. [root@berloga root]# uname -a
Linux berloga.shadowland 2.4.21-15.EL #1 Wed May 12 16:17:59 EEST 2004

PS. hang is in execute any tests group in batch. if run test manualy
test finished ok.
The manual test ran fine on our Athlon test system last night. Your
hang condition is only when LTP is run in batch, e.g. batch -f
yes. but one - i don`t use batch -f.
i direct start runalltests.sh or start via ltpmenu.
Tell me what you mean by direct start please. You are at the bash
prompt and you enter "./runalltests.sh"? You run the command as root?
If this is the case then I do not see the hang condition on my Athlon
based system. I can put the LTP software package I used on a http
site. Would you be interested in using that software to verify your
1. yes - i login as root - start xfree with kde desktop and in
kconsole start ./runalltest.sh
2. ok. put you LTP package at web and i try to run it at my system.
if it not been hanged - it LTP bug. or i can put my LTP directory for
Please use the LTP software located at
http://people.redhat.com/peterm/ltp/. Please update bug entry with
the results of your test.
with that lpt distributions tests worked as expected.
Thanks for you work.
Ð¡an I get from you news versions of LTP adapted for RH ?
If the April version meets your requirements then please use it for
the short term.
The next step is for me to use the latest unmodified version from LTP
to see if it hangs on my Athlon system.
Update with download information so I can get a copy of your exact LPT
version that is hanging.
I will follow up with my findings.
I try to use last LTP version available at LTP site.
or you can download my cvs snapshot
All of it`s copy's hanged at start tests.

task trace log
It`s look a strange but today my workstation hanged again.
I tried start you LTP suite and test locked again.
I enable sysrq and record to syslog tasks trace.
What are progress with this bug? You have any patches which i can test?
I found one bug in signal transmit and it fixed in 2.6 (bug in
__kill_pg_info) but can`t see it fix in RH kernel. Why?
Also I found Roland McGrath <firstname.lastname@example.org> posted to
linux-kernel@ mail list "[PATCH] bogus sigaltstack calls by
rt_sigreturn" who affected to RH kernel, but RH distribution not
include it. Why?
I updated my system to RH EL3 update3 via up2date. kernel 2.4.21-20
# rpm -qa | grep glibc
but bug still here. What information need for fix it ?
hm.. know i try use ltp again, and found what is trigered this bug.
If i run ltp tests from bash shell it run ok, but if i start
runtest.sh from mc 4.6.0 i seen this bug.
*** Bug 146023 has been marked as a duplicate of this bug. ***
This bug exist at last RH EL4 kernel - 2.6.9-11.
Closing out this request as notabug for RHEL3, ltp from bash works properly.
