I got two hard hangs in 2.6.32-rc5 and rc6 in an Asrock A780GXE/128M
with AMD 780G+SB700 chipsets, resulting in no response to magic alt-sysreq.
The first hang left no log clues. The second was closely but not
immediately preceeded by syslog ATA error messages (see excerpt).
They occurred days apart, possibly associated with keyboard or
mouse operation. Each hang, both tuner cards were active, with heavy
concurrent graphics, SATA and USB activity. The system has I2C and
framebuffer issues with the Radeon 7000, causing problems in the
tuners, but I don't know if it's relevant. The hangs result in no
response to magic alt-sysreq.
When tuners, USB and graphics are not active, the system passes
heavy prolonged stress testing. I got less-complete ATA-related hangs
on my previous VIA system, under similar conditions. I hoped this
new board would fix the problem. The tuner ivtv drivers could be
involved, and were known as unstable until about a year ago.
I am now disabling PMP, to see if that avoids the problem. Let me
know if you need any more information. Thanks,
Marty
