Debian Kernel Upgrade from 2.4.26-1-386 to 2.6.6-2-k7 harddrive preformance issues.
I just tried apt-getting the latest pre-compiled kernel for debian after I got everything working... I upgraded from 2.4.26-1-386 to 2.6.6-2-k7. Everything went fine except I am having extreme preformance problems on my u133/8meg cache harddrive. Switching desktops or switching backgrounds makes anything playing in XMMS skip (or pause for 1 or 2 seconds).
I ran hdparm with the -tT option to test, and then used the command
hdparm -c1 -A1 -m16 -d1 /dev/hda to turn on preformance options and ran the testing option again.
Usually, I gain about 5 to 6 megs a second on transfer rates (~42), but this time it actually decreased preformance by about that much.
I then check my /var/logs/dmesg and found only this error:
ACPI: No IRQ known for interrupt pin A of device 0000:00:11.1
which is my IDE controller card (doing an lspci):
0000:00:11.1 IDE interface: VIA Technologies, Inc. T82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)
Unfortunately, at this point I have absolutely no idea where to go / what to bang at to get this working, other then downgrading or compiling my own kernel (which is possible, I just don't really feel like it :S)
