Linux version 2.6.26.5-3.00-st20g5 (root@mzpc) (gcc version 4.3.1 (Debian 4.3.1-9) ) #1 SMP PREEMPT Fri Oct 3 12:42:56 CEST 2008
...
ALI15X3: IDE controller (0x10b9:0x5229 rev 0xc7) at PCI slot 0000:00:1f.0
ACPI: PCI Interrupt 0000:00:1f.0[A] -> GSI 19 (level, low) -> IRQ 19
ALI15X3: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x8880-0x8887
ide1: BM-DMA at 0x8888-0x888f
Probing IDE interface ide0...
...
hda: HL)DP-ST@V@-RAI CH22HP20, ATAPI TAPE drive
...
so this is a probing time device type misdectection
(yeah, the impossible has just happened ;).
Does BIOS also detect this device as "HL)DP-ST@V@-RAI"?
Please send the output of "hdparm --Istdout /dev/hda" so we can check
whether the problem is a bogus (corrupted?) identify data or some issue
with the device type detection code...
Could you also try 2.6.27-rc9?
Thanks,
Bart
