No problems either. Around the 10 of february, Arnd Bergmandd had problems with the epic100. These appeared between two revisions of the driver that differ only in the use of DMA mapping I made at the moment. Fwiw, it was essentially a matter of coding-style as on x86 the DMA mapping actually called the former virt_to_phys and pci_dma_sync was rather empty. It made no design change. It may be possible I assumed some data were in memory as they are still in some cpu registers. I'll re-re-check that. Summary: Arnd Bergmann: orig epic100 "DMA mapped epic100 (any version)" (<=2.4.0-ac9) VT8363 ok fscked but ok after bios update Daniel Nofftz: 2.4.2 2.4.3 VT82C595 ok fscked. (no mention of bios experience) Oliver Teuber: 2.2.19 2.4.3-ac7 VT82C598 ok fscked Romieu: 2.2.xx 2.4.[123] 82443BX ok ok Now it's complicated by the fact that between 2.4.2 and 2.4.3, you have DMA mapping + others changes in epic100 (they make sense imho). What happen's if you compile 2.4.2 epic100 driver in a 2.4.3 tree (I) ? [...] > Something between 2.4.0 and 2.4.3 breaks the epic100 driver. That's it. So far it's hard to say where it comes from. I would really appreciate if you could give a look at (I). If it doesn't change anything and you have spare time, some feedback from bios experience will be welcome too. -- Ueimor - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
