https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=188899 Pyun YongHyeon <yongari@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |yongari@FreeBSD.org --- Comment #9 from Pyun YongHyeon <yongari@FreeBSD.org> --- (In reply to Marius Strobl from comment #6) Marius, I was able to see 'cannot disable RX MAC' message in the attachment so I vaguely guess it could be related with incomplete controller reset. It seems Linux sets soft_bit_0 of CAS_BIM_LDEV_OEN register to force a PCI reset for old Cassini before resetting other blocks. Another thing to try is to bypass MAC/DMA stop and directly issue reset in device attach phase. I guess some of those blocks may not be in sane state before the reset so relying on some bits of CAS_RX_CONF register shall trigger other issues. I was not able to find old cas(4) controller so I couldn't test above approach though. Marius do you other clue? -- You are receiving this mail because: You are the assignee for the bug.
