=2E..Hello, here is the promised attachment :-(

Hello,

I am using Kernel 2.4.20. I admit, it is the kernel of RedHat 9.
I hope this is not, because RedHat did so much changes to the Kernel

I was just typing a mail, when the caps lock light and the scroll lock li=
ght went on.
Nothing happend anymore. No mouse, no keyboard.
I resetted the computer.

After that, I found the attached output in the /var/log/messages.
I am running cyurs-imapd, I am not sure, if it is due to cyrus.

If the buffer.c might have something to do with the filesystem:
I am using the ext3 filesystem, I have ide and scsi-drives in my system.
Here is an extract of lsmod:
ext3 69984 4
jbd 51220 4 [ext3]
sym53c8xx 67376 1
sd_mod 13324 2
scsi_mod 106168 2 [sym53c8xx sd_mod]

If you need any furhter information I will provide it.

Regards
Corneius
