RHEL 4 32bit on Tyan Thunder K8QE

Saturday, September 9th, 2006

It’s sort of a relationship between myself and this Tyan. Same server, changing demands. This time, we’ve had to install on this server RHEL4 32bit.

Net-installing RHEL4 Update 3 was impossible. See here, so we’ve installed it from CDs (didn’t have PCI-X network card handy).

When booting the server, it showed us only a single CPU. Since this machine has four dual-core CPUs, this number – one – was rather unexpected.

We’ve tried booting the system with additional parameters. We’ve tried, per RH tips, to allow “apic=bigsmp” parameter, however, when booting the server with these parameters, the server entered into reset loop. We’ve tried playing with other parameters, such as “apic acpi=noirq iommu=memaper=3 swiotlb=65536” (obtained for Google cache for a forum site which I cannot find again now), but for no avail. Finally, we’ve decided to upgrade the kernel to the one in Update4.

Doing so had special effects. When using it without any special parameters, the server entered a reboot loop, however, when we’ve added the parameter “apic=bigsmp” the server booted correcly and showed all eight CPUs.

Update – Netboot on RHEL x86 (32bit) with Broadcom (tg3) – no network

In my post just below, I have defined a set of tests to verify the possible cause of the tg3 problem. It had nothing to do with autoneg, and was fixed in RHEL 4 Update 4. That 32bit installer works correctly.

One last thing to test – rebuild the installer initrd, and replace tg3 module by one built from source (for example, HP’s tg3 drivers from the Proliant Support Pack) for this kernel. I wonder if it will work.
