 Hi, it's me again...
 
 MAINTAINER: can you reassign this bug report to: "CRITICAL", please? I 
 think this bug is "critical", indeed!
 
 I checked this on different machines. The bug seems systematic. I 
 experienced this bug on all (=4) machines I installed 5.2RC on. This bug 
 seems unrelated to kern/57174 (ata tagging), all machines have standard 
 install and GENERIC kernel config with just SMP disabled! The same machines 
 worked fine at 5.1/5.0!
 
 both ATA 0&1 crash:
 ATA channel 0:
     Master:  ad0 <QUANTUM FIREBALL CR4.3A/A5U.1000> ATA/ATAPI rev 4
     Slave:       no device present
 ATA channel 1:
     Master:  ad2 <IC35L080AVVA07-0/VA4OA52A> ATA/ATAPI rev 5
     Slave:       no device present
 
 only ATA 0 crashed so far:
 ATA channel 0:
     Master:  ad0 <ST340016A/3.21> ATA/ATAPI rev 5
     Slave:       no device present
 ATA channel 1:
     Master: acd0 <COMPAQ DVD-ROM GDR8160B/0012> ATA/ATAPI rev 0
     Slave:       no device present
 
 only ATA 0 crashed so far:
 ATA channel 0:
     Master:  ad0 <IC35L060AVV207-0/V22OA66A> ATA/ATAPI rev 6
     Slave:       no device present
 ATA channel 1:
     Master: acd0 <Compaq CRD-8322B/1.03> ATA/ATAPI rev 0
     Slave:       no device present
 
 both ATA 0&1 crash:
 ATA channel 0:
     Master:  ad0 <IC35L060AVV207-0/V22OA63A> ATA/ATAPI rev 6
     Slave:       no device present
 ATA channel 1:
     Master:  ad2 <IC35L120AVV207-0/V24OA66A> ATA/ATAPI rev 6
     Slave:  acd0 <Compaq CRD-8322B/1.06> ATA/ATAPI rev 0
 
 I just "need" heavy io load over a longer time (>5 mins) to crash the ata 
 system. I just rebuild bogofilter's spam databases to crash the machines:
 
   #/bin/sh
 
   for i in /mail/data/user/progon-net/Archive/Spam/2003-11/*.
   do
           echo $i
           bogofilter -c /etc/bogofilter.cf -s < $i
   done
 
 If you need more information, just drop an email...
 
 Best regards,
