From: Holger Kipp To: bug-followup@FreeBSD.org, ianf@za.uu.net Cc: Subject: Re: kern/51982: [sio] sio1: interrupt-level buffer overflows Date: Tue, 28 Feb 2006 12:01:07 +0100 I experience the same with FreeBSD 6.1-PRERELEASE! I just recompiled my kernel with the suggested change to sio.c, and the problem goes away... hmm. On a side note, since I changed the pci-slot (such that the PCI-800H-card didn't share the same irq with the adaptec scsi-controller), reboot does not work properly (system hangs after printing 'all buffers synced') so I have to powercycle manually, leading to the waring "/ was not properly dismounted".

And yes, the system is an old and slow PIII with 500 MHz only, but I have this problem even if only one modem is in use (sio12). I also don't know why the card can't use fast mode, unless this is because it looks like 2 cards with 4 ports that share an irq. --- 8< ----- dmesg ---------------------------------------------------- Copyright (c) 1992-2005 The FreeBSD Project.
