32-bit x86, PDC20268 controller, IBM IC35L060AVER07 PATA drive.
Kernel is 2.6.24-rc4 plus two local patches (linuxpps & EDAC) that
have nothing to do with IDE.
The circumstances are perhaps a bit odd. I have hdi in a removeable
drive tray (aluminum "mobile rack"), and had left it powered off when
starting multi-user mode. Starting the hddtemp daemon produced some
complaints and a stuck task, so I turned the drive on and tried "hdparm
-w /dev/hdi" to clean things up, and I got the following BUG message.
Now that I'm in this state, it's perfectly repeatable.
Not exactly a common situation, but I figured a BUG() is always worth
reporting.
hdi: task_no_data_intr: status=0x65 { DriveReady DeviceFault CorrectedError Error }
hdi: task_no_data_intr: error=0x65 { DriveStatusError UncorrectableError AddrMarkNotFound }, CHS=2056/8/8, sector=0
