Subject: Re: Linux 2.6.20-rc1

Hi Linus,

`hddtemp' has stopped working on 2.6.20-rc1:

[root] 19:25 [~] hddtemp /dev/sda /dev/sdb /dev/sdc /dev/sdd
/dev/sda: ATA WDC WD2500KS-00M: S.M.A.R.T. not available
/dev/sdb: ATA WDC WD2500KS-00M: S.M.A.R.T. not available
/dev/sdc: ATA Maxtor 6B200M0: S.M.A.R.T. not available
/dev/sdd: ATA Maxtor 6B200M0: S.M.A.R.T. not available

Stracing the binary reveals:

ioctl(3, SCSI_IOCTL_GET_BUS_NUMBER, 0x7fffe8a0636c) = 0

ioctl(6, SG_IO, 0x7fffe8a06240)         = 0
ioctl(6, SG_IO, 0x7fffe8a05d20)         = 0

Is there a known workaround for this?

SMART is enabled in the BIOS and it's available in 2.6.19.
