Re: panic: sorele

Well, I only have squid in my machine and although I have 1 cpu. I am 
using hyperthreading. So probably the problem is associated with SMP as 
Vlad mentioned. I didnt try to compile kernel without SMP but I will try 
it next time my proxy crash. I also do not want anymore crashes on my 
production server.

I have lots of parts of the GENERIC kernel conf file commented out but 
these are my additions to GENERIC kernel below.

Funny coincidence because I also mingled with process size things in my 
box as Vlad did...Might be something about those?

My squid process is about 1500mbyte now so... I needed to increase the 
maximum process size and I needed to adjust shared memory stuff because 
of the requirements of diskd of squid.

By the way, what is the difference between
options         MAXDSIZ="(2048UL*1024*1024)"
and
options         MAXDSIZ="(850*1024*1024)"
I mean the UL part :)

ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=xxx


FreeBSD 6.0-CURRENT with GENERIC kernel built 27th Sep.
On a SunBlade 100 I see these messages regularly when
dma is enabled. The messages go away when I either use
atacontrol to set the mode to PIO4 or set hw.ata.ata_dma to 0
I do get data corruption on the disk if left in DMA mode.

Just FYI my primary test machine is a SunBlade 100, it seems to
be doing OK with a kernel built from this morning's source.  I've
been doing most of my builds from an NFS server though, I'll do
a check with a full buildworld which will use the local drive more.

Is the data corruption spread across both drives, or just ad1?  That
message about the cable or device being limited could be a clue.

nope, its only on ad0. ad1 seems to be fine, however it is hardly used.

Did you replace the cable of the primary channel? AFAIK on Blade 100
there's a hardware bug that causes data corruption when using UDMA66
and Sun ships them with a 40-pin cable as sort of a work-around. So
these non-ATA66 cable messages should be rather normal on Blade 100.
Not all revisions might be affected though.

Re: fsck_ffs patch testers wanted


Would you be willing to post a 4.x version of this, or send me one, that I 
can test, since I'm the one that seems lucky to get the "glacially slow" 
fsck's :(

Also, some sort of "what I should be watching for" would be nice, if 
anything ... I've got my remote techs "trained" so that they can get me 
into single user mode so that I can watch fsck using ctl-t, so I can 
install this as a seperate fsck and manually test it as required ...
