stuck on TLB IPI wait

Hi All,

Please CC any answers to my e-mail, as I'm not a subscriber to the list.

I run two nodes with identical RH-based 2.2.19 kernels with ext3 patches in a cluster using "heartbeat". I also use InterMezzo module. The nodes are Compaq DL360, 2x933 Mhz PIII, 2x36 GB HDDs on Compaq Smartarray. Node #1 has 256MB RAM, node #2 has 512MB RAM. Distribution is RedHat 6.2.

Followed by messages from heartbeat the mail1 is down and is it taking over the resouces. After that everything functions normally. Please note that I'm running with "noapic", otherwise system often freezes when it initializes the network cards - I can press the keys, but apparently all IO is blocked as there is no response. These "freezes" happen with all kernels I tried, both RedHat and clean kernels from linux.org.
