After all, this is why monitoring is important ;) Yes, the machine is question is hanging after a few minutes of load. :/ I just wonder that there are 6 different tempereature sensors around, and that there were three at 35-45? and three at 70-80?, so it looks like a wrong multiplier has been applied to one set. > I remember one post on LKML about the S2882: > http://marc.theaimsgroup.com/?l=linux-kernel&m=108237636318994&w=2 > You may want to get in touch with that person and share your experience together.

The broken machine is currently unavailable, but I have an S2880 to test this (same error message): # sensors adm1027-i2c-0-2d adm1027-i2c-0-2d Adapter: SMBus AMD756 adapter at 50e0 ERROR: Can't get alarm mask data!

I can read the "alarm" file, sensors is looking for "alarm_mask" which does not exist: # strace sensors adm1027-i2c-0-2d 2>&1|grep -10 /sys/bus/i2c/devices/0-002d/alarm close(3) = 0 open("/usr/lib64/gconv/ISO8859-1.so", O_RDONLY) = 3 read(3, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\0\6\0\0"..., 640) = 640 fstat(3, {st_mode=S_IFREG|0755, st_size=1054608, ...}) = 0 mmap(NULL, 1052720, PROT_READ|PROT_EXEC, MAP_PRIVATE, 3, 0) = 0x2a97be7000 mprotect(0, 1044528, PROT_NONE) = -1 ENOMEM (Cannot allocate memory) mmap(0x2a97ce7000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 3, 0x100000) = 0x2a97ce7000 close(3) = 0 fstat(1, {st_mode=S_IFIFO|0600, st_size=0, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a97ce9000 open("/sys/bus/i2c/devices/0-002d/alarms", O_RDONLY) = 3 fstat(3, {st_mode=S_IFREG|0444, st_size=4096, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a97cea000 read(3, "16530\n", 4096) = 6 close(3) = 0 munmap(0x2a97cea000, 4096) = 0 open("/sys/bus/i2c/devices/0-002d/alarm_mask", O_RDONLY) = -1 ENOENT (No such file or directory) open("/sys/bus/i2c/devices/0-002d/in0_input", O_RDONLY) = 3 fstat(3, {st_mode=S_IFREG|0444, st_size=4096, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a97cea000 read(3, "13\n", 4096) = 3 close(3) = 0 munmap(0x2a97cea000, 4096) = 0 open("/sys/bus/i2c/devices/0-002d/in0_min", O_RDONLY) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=4096, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a97cea000 read(3, "0\n", 4096) = 2 -- Axel.Thimm at ATrpms.net -------------- next part -------------- A non-text attachment was scrubbed...
