I've added a wee bit of code to lmmon so that it
can get the xeon temperature using its onboard measurement
(which is smb). This is working fine on xeon's up to 2.4GHz.
I've got a new board in with dual 2.8GHz parts, with a 533MHz
FSB. When I run the same program on it, I get:
ichsmb0: device timeout, status=0x42
and then (usually) the board locks up.
I'm running 4.7 release.
I'm doing something like:
unsigned char byte;
struct smbcmd cmd;
cmd.data.byte_ptr = &byte;
cmd.slave= 0x18;
cmd.count= 1;
ioctl(fd, SMB_READB, &cmd);
as root, and fd = open("/dev/smb0", O_RDONLY);
Does anybody have any suggestions?
