Hi all,
Sorry my chipset is PR440FX (not 440LX as mentioned previously). Same
results on upgrading to 2.2.14+RTLV2.2. I have observed on my machine a common
error message of "kernel NULL pointer dereference....." just after the "RTL
started" message in the kernel log messages file (/var/log/messages). Kernel
is getting stuck even while it is booting. I have attached a snapshot of one
of the booting sequence messages from the /var/log/messages file. You can see
the "stuck on TLB IPI wait (CPU#0)" message in the file a couple of times
while booting. Hope this helps in getting at a solution.
I hope there are people successfully using a SMP machine. I would like to
know their configuration and the kernel versions they are using. I am unable
to run RTLinux on my machine at all. Hoping to hear for your solutions......
Surya.
