Re: Thoshiba Tecra 8000 with 3com 3CXFE575CT

Doug,

Thanks a lot for the reply. This indeed resolved the watchdog timeouts
on my 3c575B. Still would be great if this were fixed for non-polling.
Now acpi seems to be misbehaving, a fan that used to stop when the CPU
< 62C now continuously runs.

Spil.
