Oracle 9.2.0.1.0 upgraded to 9.2.0.5.0 can't parse linprocfs?

[Eugene Grosbein]

Hi!

We were running Oracle 9i (9.2.0.1.0) with FreeBSD 5.0-CURRENT
(then 5.2.1-R, then 5.3-STABLE) for a year without a problem.
Lately he hit one of Oracle's internal bugs and were forced to upgrade
Oracle 9i upto 9.2.0.5.0 using patchset.

Upgrade went just OK, though I was forced to replace
/compat/linux/etc/redhat-release with new content for Oracle Installer
start to work: Red Hat Enterprise Linux AS release 3 (Taroon).

Now Oracle can't start properly. It seems it fails to parse
a file from linprocfs. kdump shows that it reads
/compat/linux/proc/10494/stat (where 10494 is a PID of newly started child)
and breaks immediately saying that sscanf is failed:

 10476 oracle   CALL  open(0xbfbfb72c,0,0)
 10476 oracle   NAMI  "/compat/linux/proc/10494/stat"
 10476 oracle   NAMI  "/compat/linux"
 10476 oracle   NAMI  "/compat/linux/proc/10494/stat"
 10476 oracle   RET   open 10/0xa
 10476 oracle   CALL  read(0xa,0xbfbfb764,0x3e7)
 10476 oracle   GIO   fd 10 read 113 bytes
       "10494 (oracle) 0 10493 10494 10494 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 311\
        750656 25752 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
       "
 10476 oracle   RET   read 113/0x71
 10476 oracle   CALL  close(0xa)
 10476 oracle   RET   close 0
 10476 oracle   CALL  mincore(0xbfbfb6f0,0)
 10476 oracle   RET   mincore 0
 10476 oracle   CALL  close(0x6)
 10476 oracle   RET   close 0
 10476 oracle   CALL  open(0x5001a53c,0x8441,0x1b4)
 10476 oracle   NAMI  "/compat/linux/home/oracle/9.2.0.1.0/admin/orcl/bdump"
 10476 oracle   NAMI  "/home/oracle/9.2.0.1.0/admin/orcl/bdump/alert_ORCL.log"
 10476 oracle   RET   open 6
 10476 oracle   CALL  old.killpg(0x6,0xbfbfb6f4,0x2)
 10476 oracle   GIO   fd 6 wrote 79 bytes
       "skgpspawn failed:category = 27143, depinfo = 22, op = sscanf, loc = sk\
        gpstime5
       "
 
So I ask, does contents of /compat/linux/proc/10494/stat shown above
looks right? I do not have a RedHat box to compare format.
Perhaps, I should upgrade installed linux_base-7.1_7/linux_devtools-7.1
upto linux_base-8.0?
