SubjectWrong priority reporting with new 0(1) scheduler; USB changes to 2.4.18 pre/rc1 breaks HPOJ
Date
Priority reporting issue:

I've applied the 0(1) scheduler patch in conjunction with the preemptible
patch to 2.4.18 pre (sched-O1-2.4.18-pre8-K3.patch and
preempt-kernel-rml-2.4.18-rc1-ingo-K3-1.patch)

I found that top and other process managers (like kpm) report the priority as
9 instead of 0 for nice level 0 applications with the preemptible patch, and
15 with both preemptible and 0(1). Nice'd applications can have their
priority reported as high as 39. It seems to read it as 15-20 higher than
the nice value. The kernel appears to work flawlessly otherwise.


USB issue:

The USB changes after 2.4.17 up to and including 2.4.18 rc1 cause the hp
officejet drivers to fail on my machine. While the usb mouse continues to
work, the hp ptal-init probe cannot find the device when scanning
/dev/usb/lp0. The device is still reported correctly in
/proc/bus/usb/devices. This is with both the usb-uhci and the uhci drivers.

Hardware configuration:
Soltek 65KV apollo pro via motherboard with PIII 933. HP Officejet G55.
