Comment 16 for bug 238118

I deinstalled linux-image-2.6.20-xen with dpkg -r and installed your kernel with dpkg -i

ls -l /root/linux-image-2.6.24-20-xen_2.6.24-20.37_i386.deb
-rw-r--r-- 1 root root 18747646 2008-07-23 22:21 /root/linux-image-2.6.24-20-xen_2.6.24-20.37_i386.deb

I was a bit confused because the kernel is much older than the deb:
ls -l /boot/vmlinuz-2.6.24-20-xen
-rw-r--r-- 1 root root 1732665 2008-07-18 01:06 /boot/vmlinuz-2.6.24-20-xen

uname -a
Linux xenserver2 2.6.24-20-xen #1 SMP Thu Jul 17 23:00:58 UTC 2008 i686 GNU/Linux

and also the modules

ls -l /lib/modules/2.6.24-20-xen/kernel/drivers/scsi/aic7xxx/
-rw-r--r-- 1 root root 356352 2008-07-18 01:07 aic79xx.ko
-rw-r--r-- 1 root root 220892 2008-07-18 01:07 aic7xxx.ko

I also do not get the message with XXX, but

Since the kernel BUG line refers to a file in /home/smb and not anymore to /build/buildd/ I assume that I didn't make a mistake when installing the kernel. Could it be that something went wrong when compiling the kernel/building the package? Maybe no make clean before?

Please let me know it I should do something different or if you have a new deb for me.

I will also try the kernel options when you tell me which parameters I should test. I found the swiotlb option in some mailing list before and tried 65536, but I got a crash during boot time...

Thanks,

Timm

P.S.: Sorry if you receive this twice. I was not sure if my mail went through...
