Hi folks and D. Stimits,
Summary of discussion taken place so far (for linux-kernel people):
D. Stimits noticed he can not boot his kernel from a 1.44MB floppy
created with "make bzdisk". This would lead into a register dump. The
dump does show the boot code tries to read track 80 of the disk.
Hi,
had an Oops in __mark_inode_dirty running kernel 2.4.2-pre3 on i386 UP
(actually a PII-300). It did happen during the daily cron job. Currently
on proc, devpts and ext2 filesystems are used no nfs and the like. The
system is still running. So if you need further information mail me or
come on

Hi Alan and folks,
I got asked why it gives unresolved symbols (and how to fix it) for the
I2O modules. During the session I noticed this is due to the fact the
I2O core is built into the kernel but the other I2O support built as
module. So the quick hack to resolv that problem was adding the mi

This patch implements routine s390_cpu_model_init(). It is called by the
realize function during instantiation of an CPU object. Its task is to
initialize the current accelerator with the properties of the selected
processor model.

The patch adds optional parameters to the QMP command query-cpu-definitions.
Thus the signature of routine arch_query_cpu_definitions needs to be changed
for the stub function and all target implementations:

Hi,
with 3.14-rc4 my box does not finish initializing the LVM array. It
hangs within the call to rw_header() on line 632 of dm-log.c. See
backtrace at end. Please excuse typos within - had to type it from a
screen shot.
The problem seems to be introduced by the commit

Hi Mike,

Thanks for the fast reply. Did pull in the whole branch 'linux-next'
from the repo now. It is back to working.
