John stuff. I suspect it's natural and normal, if the IDE error handling
did something rude with interrupt holdoff.
The new libata should be more polite than that, although since the ATA
drive can stall the CPU indefinitely you lose anyway 8(
It may not be related to ATA. I just reloaded into 2.6.17-mm6 to get the info
for Alan and saw it when booting up on that too:
PCI: Setting latency timer of device 0000:00:1d.7 to 64
ehci_hcd 0000:00:1d.7: EHCI Host Controller
ehci_hcd 0000:00:1d.7: new USB bus registered, assigned bus number 1
Losing some ticks... checking if CPU frequency changed.
ehci_hcd 0000:00:1d.7: debug port 1
PCI: cache line size of 128 is not supported by device 0000:00:1d.7
Note it was in a different place in here than in -rc1-mm1 (slightly later in the
bootup).
I'm fairly sure it's not new to this release.
