Hello,
Iīve set up a Debian-2.2-System and built a Kernel-2.4.0-test11 on it.
Hardwareconfiguration : athlon-850MHz, Asus-A7V (promise ultra-100 on
board), additional promise ultra-100-card. 3 IBM DTLA 307045 Disks only
one at each IDE-channel. The three ata-100 disks should become a raid-5.
Additional small IDE boot-disk with the Debian-system. Kernel-messages at
boot-time looked fine.
After installing a raid5-array with 3 45MB-Partitions(fd) on 3 IBM DTLA
307045-Disks, i tried to boot the system. The first 2 times the kernel
crashed while outputting an oops-message. I know that itīs important to
send you the exact message, but i didnīt expect that it would go away
after the second attempt and now i just donīt have it. SORRY.
The third attempt to boot succeeded, BUT the raid array couldnīt start:

autodetecting the raid seems to work, but starting doesnīt.
This looks to me like the kernel kicks 2 from 3 disks in the raid5-array
because of a kind of timestamp? and then the whole array isn`t
recoverable anymore.
I donīt know anything about that update time, but may it be better to
ignore it in advance to be able to keep the array running ?
The same thing happens when i try to start the raid manually with
raidstart /dev/md0.
In the log above you can see, that the settings for the three ibm-disks
(connected with 80-pin cables) are pio and not DMA! This log was created
at the first time the boot-process succeeded after installing the raid.
After this, i booted the machine several times and the settings were DMA,
which is correct.
Now the system is booting well, but the raid5 gives up every time.
The Raid-Disks contain no data yet, so iīll try to make the raid array
again.
But i thought this case could be important for the Kernel-Developers.
Next time i have a kernel-crash i WILL write down the output.
