Promise Ultra 100 TX2 IDE cards provoce system crash

[Fabian Lienert]

Promise TX2 IDE cards and PDC20268 driver: Last night when backup 
writing started from our Software RAID5 to the single drive, the system 
crashed, no oops messages.


I built up a Debian stable fileserver with Software RAID5 and Reiserfs.
we use:

2 Promise Ultra 100 TX2 IDE Controller Cards,
4 Maxtor D740X ATA 133 80 GB harddisks, linked by Ultra ATA cables to 
the two Promise cards. Every disk is master. We use 3 disks for the 
Software RAID-5, one as a single (no raid) backup drive.

Kernel is 2.4.18 with Support for RAID-5, Reiserfs, Promise Ultra 100 
and Server Works OSB4 IDE Controllers (the onboard controller only for a 
unused spare disk and cdrom). Didn't found this fixed in 2.4.19.

The system crashed during the backup from RAID to /dev/hde while writing 
a huge file bigger than 770 MB. This is the last log I have.

Before this crash I had another crash because of setting the drives to 
udma6. Now the drives are set with hdparm to udma5:

hdparm -d 1 -c 1 -k 1 -X69 /dev/hde
hdparm -d 1 -c 1 -k 1 -X69 /dev/hdg
hdparm -d 1 -c 1 -k 1 -X69 /dev/hdi
hdparm -d 1 -c 1 -k 1 -X69 /dev/hdk

Because the kernel sets only /dev/hdi and /dev/hdk to udma5 even if
append="ide2=ata66 ide3=ata66 ide4=ata66 ide5=ata66" or the same with 
ata100 is in lilo.conf.
