https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262263 --- Comment #10 from Alexander Motin <mav@FreeBSD.org> --- @Lamia, there seem to be two independent issues here: one for USB, one for AHCI. Please do not mix them. I have doubts that panic you see on 14 should be reproducible on 13.1, but please correct me if I read your wrong. @trasz I think I see the problem, and it may indeed be related to your change. In ahci_issue_recovery() I see such a line: ccb->ccb_h = ch->hold[i]->ccb_h; /* Reuse old header. */ , which should also copy alloc_flags from read periph CCB to the locally allocated one. When it comes time to free the CCB, it is probably getting freed to the wrong zone. -- You are receiving this mail because: You are the assignee for the bug.
