[parisc-linux] bug report on Sym53C895a or config error?

[yuqian]

Hi.
For xc not available yet, I download Image-testcpu(2000-10-02) 
as my net-boot kernel, my HP box is HP B2000 (9000/785) with 
NCR53C8x SCSI card. At first all is OK, but the follow message is 
reported during mouting root fs, is it a bug or just that kernel's 
config not match my box?
Thanks.
BTW: Is xc not available for HP-UX 10.20 yet?
(When I type 'configure --target hppa-linux' for glibc, it told me this
is not supported yet.)
And: How can I get more information (like instruction, registers value ...)
for bug report?
