sym53c8xx_2 hangs on 53c810 rev 02

sym53c8xx_2 hangs on 53c810 rev 02

[Ingo Korb]

Hi!

While trying to run 2.6.9 on my AlphaStation 200, I noticed that 
sym53c8xx_2 doesn't seem to like the onboard 53c810 rev. 02 (see 
bootlog below).

Some posts in the archives suggested that such problems may be caused 
by older devices that may not like the defaults used by that driver, 
but the system hangs even when the only thing connected to the 
controller is a properly terminated cable.

Just going through my old bug reports ...

To be honest, this looks like the sym2 driver never received any interrupts.
Could you boot with sym53c8xx.debug=0xffff on the command line?  That should
report any interrupts that come in.

to examine any refutations of them; and thus he will by and by convince 
himself that the war is just, and will thank God for the better sleep 
he enjoys after this process of grotesque self-deception." -- Mark Twain

I guess so - I'm not sure why I reported problems with the 2.4 version
of the driver, when I just retested it with 2.4.29 everything was
working fine.
