kernel-xen-hypervisor-2.6.15-1.1977_FC5 is very slow (problem with aic7xxx?)
Last modified: 2008-01-19 23:36:59 EST
kernel-xen-hypervisor-2.6.15-1.1955_FC5 is very slow. It boots correctly but
deadly slow, I waited 10+ minutes for it to finish startup process (including
init and daemons). It seems that the kernel become slow after loading aic7xxx
module. After that all kernel messagas comes slower. The system is dual P3 1GHz
512MB STL2 Intel board with AIC7899 SCSI controller. Booting with acpi=off never
succeeds - the kernel reboots shortly after load. noapic results in scsi errors
while probing scsi bus.
Never tried other XEN version on this box. Core5 test2 kernel works fine.

These bugs are being closed since a large number of updates have been released
after the FC5 test1 and test2 releases. Kindly update your system by running yum
update as root user or try out the third and final test version of FC5 being
released in a short while and verify if the bugs are still present on the system
.Reopen or file new bug reports as appropriate after confirming the presence of
this issue. Thanks
The package this bug filled against is latest available from development tree.
kernel-xen-hypervisor-2.6.15-1.1977_FC5 is slow too. Xen 3.0.1 binary
installation downloaded from Xen website (kernel 188.8.131.52) works fine (but has
some problems with udev). 2.6.15-1.1977_FC5 when booted with xen hypervisor from
3.0.1 binary distribution is slow too.
I have serial console so I can provide any dmesg you need.
how does -1.2041 look ? That has a whole bunch of debugging stuff turned off, so
should be a lot faster at certain workloads than rawhide has been for the last
kernel-xen0-2.6.15-1.2041_FC5.i686 is slow
A new kernel update has been released (Version: 2.6.18-1.2200.fc5)

Please retest against this new kernel, as a large number of patches
