Same situation here, at different rates on two different platforms,
both running same kernel build. Both show steadily increasing biovec-1.
uglybox was previously running Ingo's 2.6.11-rc2-RT-V0.7.36-03, and was
well over 3,000,000 bios after about a week of uptime. With only 512M of
memory, it was pretty sluggish.
Interesting that the 4-disk RAID5 seems to be growing about 4 times as
fast as the RAID1.
If there's anything else that could help, or patches you want me to try,
just ask.
Details:
=================================
#1: Soyo KT600 Platinum, Athlon 2500+, 512MB
2 SATA, 2 PATA (all on 8237)
RAID1 and RAID5
