Hello! I am experiencing hard lockups (no oops, no response to ALT-SYSREQ) on a dual pentium pro running 2.4.1pre9. The system has two Promise IDE controllers installed (PDC20246 and PDC 20262) with a drive hanging off of each channel. In addition, the onboard PIIX4 has a single drive hanging off the first channel. The hard lockup occurs during heavy IO during a boot-up fsck. The system is fscking three of the four Promise channels and the PIIX4 channel simultaneously. The system locks up hard after 60-90 seconds of fscking. Since the system does not respond to ALT-SYSREQ, I have been unable to get any dumps. Does anyone have any thoughts on how to proceed?
