** Description changed: + SRU justification: + + Impact: Panic in vmware guest running Hardy (see below) + + Fix: Backport from upstream to make sure of the correct loops per jiffie + value. + + Testcase: Booting guest on a busy host + + --- + From Alok Kataria: While testing Ubuntu 8.04.3 under VMware. We have seen situations when we hit this panic in the guest, during bootup. "Kernel panic - not syncing: IO-APIC + timer doesn't work! Try using the 'noapic' kernel parameter" I had fixed this problem for mainline some time back but I guess I forgot to ask you guys to pick this patch. The direct port of the mainline commit (3da757daf86e498872855f0b5e101f763ba79499) gave a couple of trivial merge conflicts for hardy. The backport (lpj_tsc.patch) of the patch which applies to hardy-git is attached. Many user's might hit this when they start running 8.04.3 guests, so it would be great if you could apply the fix at your earliest. Please note that, with VMware hypervisor specific changes which went in the 8.04.3 kernel (tsc improvements) the likelihood of anybody hitting this on AMD systems is slightly increased. Other Newer Ubuntu releases already have the fix from mainline.
