Subject: 3.1.3 2.6.37.6 2.6.33.4 kernel bug in pata_oldpiix driver
I have discovered a bug in the oldpiix pata driver in kernels 2.6.33.4 and
2.6.37.6 from installation CD of Slackware 13.1 and 13.37.
The pc is a Pentium 133MHz, 64MB RAM, mainboard Freeway 586F61-PB, Chipset i430fx Intel
Triton I, 80GB IDE HD Hitachi. Memtest is OK.
The bug is repeatable, and stable under many kernel configuration changes.
The error messages are all very similar.
Changing the config of 2.6.37.6 from "Voluntary Kernel Preemption (Desktop)"
to "No Forced Preemption (Server)" the bug *apparently* disappears.
Actually it reappears making subsequent changes to config, e.g.
deleting drivers.
The bug does not appear in 2.6.38.7, 2.6.39.4, 3.2.0rc3.
But reappears in 3.1.3. (all these one compiled with GCC 4.4.4)
For safety's sake, I have switched back from PATA to the oldpiix IDE driver.
No problem from IDE driver, for years the machine ran 2.4.29 flawlessy.
I append here only the relevant error trace and lspci output.
I attach also a tar file containing complete dmesg (through serial port) and
configs of kernels 2.6.37.6, 2.6.33.4, and 3.1.3.
Hope it helps.
