| |
Hi everyone,
After installing noflushd daemon, I noticed it couldn't access the disk_io stats for all IDE disks attached to my system, but only the attached to the motherboard IDE controller. The ones that doesn't appear in /proc/stat are the disks attached to a Promise Ultra66 PCI IDE card. I reproduced this problem with 2.4.18, 2.4.17 and 2.4.7 kernels.
The dmesg log says:

Is there any patch that could be applied to the 2.4.x kernel series to get this thing working?
Thanks in advance,
